I don't think the heat from a joint or bong is hot enough to burn the minerals. I know people use wood ash in their gardens so there must be some kind of nutrition still in it. Just offering a thought not stating anything as fact.
400-700c is pretty hot.

Priorities.

If you live in the United States, there is a nearly one-in-four chance your tap water is either unsafe to drink or has not been properly monitored for contaminants in accordance with federal law, a new study has found.

Clean nutrients is a good start thou.

I guess due to all the deaths reported of marijuana growers and smokers we should move forward with this important study...said with tongue firmly implanted in cheek...pfffft !!!

Autism is not on the list. Why use a nutrient with a color anyway? So don't! The VAST majority of quality synthetics' use NO DYE'S - period!

Don't even bother to bring up how many are "brown". That's from the use of kelp as a source.

: The problem here is if it's mixed with citric or ascorbic acid!

: BHA is the real bad one - you missed that.
So give me a list of nutrients that actually contain these......I want to know.......All the top rated lines and the ones I find as quality - Do NOT contain them! Even the supplements......

Heavy metals are the Real main problem sport!.



Neither are Organic - Other then source materials used..... None of the packaged Poo's, meals or compost's, or anything used to build soils are "regulated" either.... So any point your trying to make by using the word "regulated" is moot!



MANY of the top nutrient lines were intended for food production - In fact designed for it! Everything from herbs, tomato's and even vine crops!

How about you take a look at the leading outlet for US hydroponic production growing. American Hydro.
https://amhydro.com/

Look around a bit? Notice that they custom blend to your needs? They formulate their own nutrient formula's to what you grow.
How about you call them and ask about what's in their products.

Farmtek is another that carries Hydrofarming supplies. With a large selection of equipment, for nutrient lines. They feature Botanicare and Flying Skull products only.

These 2 are just the tip of the iceburg.....Once you get to Europe, it truly expands! Some hydrofarms in the Netherlands are expansive and serve to the whole EU.

There are world wide debates on just what is more healthy, soil or hydro...... They are heated and still go on, all the time.

So then sir. I find your statements as reactionary and overblown!
You are not specific on any label(s) and as far as preservatives go. Your only reacting to another members comment...
You show no real, knowledge of nutrient contents and the section on pg 1 you posted is no more then an internet cut and paste job from an old notice.

On that, like I said before. "Bad" PGR's are not used anymore.....

Nutrient bottle contents are reported far more then you think! Simply look at Oregon's listing of all available things and it's simple to choose from there....Don't you think?

The real issue is heavy metal content! Know why?
Because MJ is an "accumulater" plant...... Metal levels build in MJ! Being aware of that, is a very important issue in growing medicine!

Your making a mountain out of a mole hill, and attempting to scare the uninformed.

The VAST MAJORITY of available nutrient lines are safe for use to grow MMJ. It's simply up to you to do any research into the questions you may have to decide what one you want to use.

Please stop the grandstanding.



Respect bro, thanms for loving my copying and pasting. Couldn't be bothered to remember and put it in my own words like you bro.

Do we have a heavy metal build up in organic fed cannabis plants or it is just in chemical fed ???????

As I said before I ain't telling nobody to believe me or anybody else. We're all sharing our thoughts and facts.

Yes the copy and paste below is from a reputable source, Jorge Cervantes!


Nutrients build up in plant foliage and tissue, especially in cannabis that is “pushed” hard with fertilizers. Synthetic salt-based fertilizers are the worst. Often indoor growers add large amounts of phosphorus (P) and potassium (K) during flowering. The nutrients can build up in plant tissue adding weight.


Greenhouse and indoor gardeners that grow in containers and hydroponics can leach fertilizer salts from soilless mixes and hydroponic substrates in 5-7 days. Light well-aerated soilless mixes consist of peat and/or perlite, and may or may not be impregnated with nutrients. Salt-based nutrients are easy to leach when in containers. Gardeners must leach soil with 3 gallons of clean water for every gallon of growing medium.

For example, if a flowering plant is in a 5-gallon container, the grower would need to leach with 15 gallons of water daily for about a week for a thorough “flush.”


I hope you you have big arms and a strong back, because all you chemical growers will have a hell of a time Flushing .

I found this online at it was written in 2015, thought I'd post it for everyone .


If you use marijuana – whether as a recreational substance and especially if you use it as a medicine – what is far more important than the strain is how the plants are grown.
Most growers, even if they advertise their product as “organic,” use nutrients that contain compounds known as plant growth regulators (PGRs) to compete on price or use toxic pesticides to save crops from diseases and pests.
PGRs are chemical substances that profoundly influence the growth and differentiation of plant cells, tissues and organs. Plant growth regulators function as chemical messengers for intercellular communication.
In today’s cannabis market, competition is extreme. Even a casual glance at local newspapers that carry ads for marijuana dispensaries will reveal that the competition is all about price. Marijuana that used to cost $400 an ounce now sells for less than $100. This makes the use of PGRs to dramatically shorten growing times and increase bud weight compelling.
Unfortunately, as with many things, when consumers buy into this game, the consumer gets what they pay for. They may get a gram for $4, but what they don’t realize is that they may be setting themselves up to develop serious health issues including cancer, neurological problems, liver problems and much more.
Product advertised as “organic” and offered at $4 – $6 a gram should be a big danger sign for responsible consumers. The cost of growing truly organic marijuana without PGRs and toxic pesticides makes such pricing impossible.
Contrary to what the manufacturers of PGRs and the many growers who use them might claim, PGRs are not the same as natural plant hormones. They are synthetic chemicals specifically designed to moderate plant behavior, and many are extremely toxic.
Remember that marijuana is a cash crop. Each plant in can be worth up between $500 and $1,000. Because most growers are motivated by profit, it becomes easy to justify the use of products that dramatically shorten flowering time, increase bud weight, or both.
Due to their extremely toxic nature, most PGRs have been banned for use in food crops since the 1970s but are still widely used in the cultivation of marijuana today. Because marijuana is considered an illegal drug at the level of the federal government, the FDA and other government agencies refuse to either regulate PDRs or inform the public about their dangers.
Because marijuana cultivation has become such a huge business, manufacturers take advantage of this situation. Formulators are not always required to list every ingredient in their products; claiming that their recipes are “trade secrets.” When marijuana is grown with products that make this claim, the consumer should see it as a big red flag.
The California Department of Food and Agriculture (CDFA) tested several products, and the findings have since been made public, thanks, in part to the Freedom of Information Act.
Bushmaster, Top Load, Flower Dragon, PhosphoLoad, and Gravity are just a few of the products that are popular among growers. This is not an exclusive list. There are many others. Not only are these products toxic, but also how they are marketed is extremely deceptive, often leading well-meaning but uninformed growers to think that the products are actually “organic” or at least “all-natural.”
Thanks to the CDFA report, we now know that Gravity does, in fact, contain a PGR called Paclobutrazol (PACLO.) In plants, this chemical retards internode length and reduces maturation time significantly. When used on marijuana, this results in tighter flowering tops that can be harvested much earlier.
This has made Gravity an attractive fertilizer additive to many unsuspecting or downright unscrupulous growers. Unfortunately, tests on rats demonstrate that the product may cause serious liver damage and could be highly carcinogenic. Paclobutrazol is only one of many toxic PGRs used to cultivate marijuana.
Other alleged PGR tainted products include: Superbud, Purple Maxx, Boonta Bud, Rox, Rock Juice, Cyco Flower, Yield Masta, and Mr No. There are many others.
So how can you become an informed consumer? Unfortunately, it isn’t easy. Many nutrient manufacturing companies that growers trust and give their money to – including General Hydroponics, Dutch Master, Humboldt Nutrients, Emerald Triangle, Humboldt County’s Own, Hit Manufacturing, and many others, have included PGRs in their products, and have thereby endangered the health of consumers of marijuana!
Labels for these products rarely if ever mention PACLO or any other toxic PGRs.
They only talk about kelp, humic acids, amino acids, phosphorus, and potassium. All of these products sound natural and benign. There is absolutely no mention of anything that’s dangerous. That is no accident.
Because manufacturers of hydroponic nutrient solutions aren’t required to list all of the ingredients in their products reading labels isn’t very helpful. Growers pick up a bottle of something because of its reputation. Sellers say: “Trust me, I don’t know why it works – it just works.”
When ingested, many of these products are neurotoxic and carcinogenic to human beings. Some of these PGRs break down into other metabolites that are even more toxic than the original substance.
Pesticides
Besides PGRs, there is another class of toxic chemicals used in the production of marijuana, and that is pesticides.
Remember, the financial repercussions of pests like spider mites or diseases like powdery mildew can be severe to a marijuana grower who depends on the success of their crop to sustain cash flow. Imagine a company that has a 50,000s square-foot grow facing a powdery mildew outbreak. That could easily cost that grower over $1,000,000. What about the small grower who grows out of his home as a care-taker for a small number of patients? For many, the temptation to use these products is just too much to resist.
How toxic can they be? One typical product is Eagle 20 Pesticide. Here is what they say on the label: “Inhalation may cause central nervous system effects. On animals effects have been reported in the liver, testes, adrenal gland, kidney, and thyroid. Contains chemicals known to cause cancer. Eagle 20 is considered by the EPA to pose both an immediate and a delayed health hazard.”
The fact that Eagle 20 is a known endocrine disruptor is the most concerning. Endocrine disruptors are chemicals that interfere with endocrine (the hormone system) in animals and humans even at extremely low doses. These disruptions can cause cancerous tumors, birth defects, and developmental disorders such as learning disabilities, severe attention deficit disorder, cognitive and brain development problems, deformations of the body, sexual development problems, feminizing of males, and masculine effects on females.
Worse yet, if a developing fetus is exposed to and affected by endocrine disruptors, it can take decades for adverse effects to manifest. Even more disturbing, it appears that the effects of endocrine disruptors are passed from generation to generation through epigenetic modification of our DNA. Some research indicates that the effects are trans-generational, meaning that the hazardous health effects can be passed on for multiple generations.
So not only can exposure to products like Eagle 20 cause hazardous health effects in you, but they can also cause hazardous health effects in your children, and possibly even you grand-children, decades after you were initially exposed.
So what should the responsible consumer of these products do?
1. Start by realizing that cheap marijuana is no bargain – no matter how compelling the ads, and no matter what the grower may say. Good, organic or all-natural top quality bud should cost at least $8 if not $10 or more a gram. That is because grown naturally, marijuana takes longer to grow, will require more nutrients and more expensive nutrients, and will not produce the weight of product grown with PGRs.
2. Also realize that while lab reports in Colorado test for potency and may identify products contaminated with pesticides, metals, and solvents, they typically do not report the presence of PGRs. WOW !!!!! This means that just because a product has been tested by a lab, it doesn’t mean it is safe from these substances.!!!!!!!!!!!
Conclusion: While marijuana can be a powerful medicine for many health conditions, if grown using PGRs and toxic pesticides, it can be a tremendous health hazard. Unscrupulous or uneducated growers pose a major risk to unsuspecting consumers. Especially if you are a cancer patient or someone suffering from neurological problems, liver or other digestive issues, or chronic viral infections like AIDS.
There are many cannabinoids that are known to be powerful medicines for diseases like cancer, multiple-sclerosis, diabetes, Crohn’s disease, arthritis, PTSD, and more. Of these cannabinoids, cannabidiol or CBD is emerging as one of the most important.
It is therefore no surprise that CBD medicines are now starting to proliferate in the market. However, most of these use CBD oil that originates in China. Lab tests reveal that such oil contains high amounts of heavy metals like arsenic, mercury and cadmium. No cancer patient would ever want to take high levels of arsenic. It would be like throwing gasoline onto a fire.

What is Organic?
In the United States, the term "organic" is federally regulated and governed by standards in the Code of Federal Regulations only when used on food or fiber products. Food and fiber products that use the term "organic" are required to be certified by an independent third party certifier, with an exception for very small-scale producers with earnings below a certain amount. All producers that use this term are required by law to follow organic practices. The term "organic" is not currently regulated for many non-food products such as pet food, cosmetics, household products and fertilizers. These products may meet non-government, privately maintained standards, but the use of the term "organic" on labels is not federally regulated for these non-food products. For example, a fertilizer may be "OMRI Listed," meaning that it meets OMRI's standards for a fertilizer, but almost any fertilizer can use the term "organic" on the label. Canadian laws are similar regarding what can and can't be called "organic."

To become certified organic, a conventional farmer must first undergo a three-year transition period, during which time no prohibited inputs can be used. Organic certifiers can provide support for the transition process, helping the farmer understand and follow the organic standards. Once the three-year period is complete, the farmer can start to produce organic food. The farmer completes an "Organic System Plan" that explains how the food will be produced, including a list of all inputs that will be used, and the farm undergoes an annual certifier inspection.

What about yield?
You'll never quite get the yields from soil that you can from hydroponics no matter if you use nutes or not. This is mostly due to time; plants in hydro simply grow faster so the same yield requires less veg time than it would in soil. The difference is better quality & flavor of the bud so there is definitely a tradeoff. Yields indoors are mostly governed by wattage so you can get comparable yields in a dirt pot if you spend more time training and vegging even though it does take longer to get there.

Yes just because it says it's organic doesn't mean it is safe for the microbial populations that live in the soil. Look for the OMRI label to be sure. In the US the word organic is just a marketing term; it doesn't mean shit because there's no regulating entity enforcing what is organic & what is total bullshit.

Oh boy, here we go!

Do we have a heavy metal build up in organic fed cannabis plants or it is just in chemical fed ?
Both! MJ is an "accumulator" plant. It up takes and stores. More on this later.

Yes the copy and paste below is from a reputable source, Jorge Cervantes!
Jorge, sigh. Jorge is an old hippie grower. He writes books on growing MJ. He has zero (0), non, nada actual schooling or training in Horticulture, Botony, or plant biology. His theories on some things are, um, basically - dead wrong!
With that said - lets look at exactly what he said in your quote.


Nutrients build up in plant foliage and tissue, especially in cannabis that is “pushed” hard with fertilizers. Synthetic salt-based fertilizers are the worst. Often indoor growers add large amounts of phosphorus (P) and potassium (K) during flowering. The nutrients can build up in plant tissue adding weight.
Partly true: The plant will store a limited (in a sense) amount of P&K and other nutrients. Once that limit is reached. The plant reacts by showing you over feeding signs. The more you keep feeding that nutrient, - the worse it gets. The most common one around here is P tox or high P conditions that cause early yellowing of the leaves, from the bottom up. While the plant is in bloom. The reason for this (90% of the time) is folks start using a high (to high, too early) P/K bloom food that has reduced N levels. N levels should not be lowered for several weeks into bloom. Even then, it is strain dependent!

Synthetic salt-based fertilizers are the worst.
NOT TRUE: You can overfeed with organic nutrients - just as easy as with synthetic. Synthetic will simply show the problem faster.....

The nutrients can build up in plant tissue adding weight.
Very misleading statement: The "weight" thing would be measured in milligrams - per plant - maybe and I mean maybe thousanths of a gram! These and other nutrients are broken down by the proper drying and curing of your crop....

Greenhouse and indoor gardeners that grow in containers and hydroponics can leach fertilizer salts from soilless mixes and hydroponic substrates in 5-7 days. Light well-aerated soilless mixes consist of peat and/or perlite, and may or may not be impregnated with nutrients. Salt-based nutrients are easy to leach when in containers. Gardeners must leach soil with 3 gallons of clean water for every gallon of growing medium.

For example, if a flowering plant is in a 5-gallon container, the grower would need to leach with 15 gallons of water daily for about a week for a thorough “flush.”
PARTLY TRUE & THE REST (FLUSHING) IS TOTAL BULL SHIT: Lets take this in 2 parts.

#1: The part about removing nutrients from soilless mix's (hydroponic substrata) is only correct to the point that you have removed or reduced the nutrient available to the plant. You have not reduced the nutrient in the plant!
#2: FLUSHING IS A MYTH! You can not "flush" nutrients from a plant - period! The plant does not biologically work that way......Starving a plant to reduce the nutrient levels in the plant. Wont really work either! As the plant draws from the actual reserves (mostly in the roots - then onto leaves) the nutrients are moved to where the plant is actually using them, the buds! So your not removing nutrients from the buds but, replacing it. In the long run your actually hurting the potential yield by this practice. This is actual plant science - not 70's hippie logic!

Now the rule applies to organic's too! Thing is, it's DAMN hard to "flush" organic nutrients from the soil. So then, using Jorge's "logic"....Why is organic grown better tasting?

Does this clear a few things up?

This part, I'm more then familiar with......I manage an organic farm co-op of now 4 farms, including a dairy farm that is still one year to go in the "transition".

Nice post.

So then, I hope you learned something and I'll point out again. Heavy metals are a big concern. The biggest one I have for our farms soils and therefor the contents in the produce/grains we grow for market....

I learned the hard way that organic amendments can hurt your plants. This fox tail is in a very heavy clay soil which I believe is high in phosphorus. I added a high phosphorus back guano to this plant. It was green before and I'm pretty sure the guano did this. I could be wrong though I often am.

This is the second time I have enjoyed your posts and gone digging through your post history. I wish I could tag members. Thanks for sharing some great information.

On the topic of flushing, although I hate to use the word, is there any benefit to decreasing nutrient levels prior to harvesting? I've heard many complaints about the dread hay taste that comes with hydroponics, what's your view on that? I use a 3-1-2 for veg, 2-2-3 for flower and then a 1-4-5 for the last few weeks - if that's of any significance. I also start with high calcium and decrease it (3.6, 2.5 and 1.25 respectively) and keep a constant 0.5 part of sulfur throughout my grows. I only have one grow under my belt and would really appreciate your insight on the topic, alternatively if you could point me in the direction of some relevant reading?

Why thank you....

Possible but, in all the time I've been doing this. I haven't found one that has any real effect on result. Other then not overfeeding. However, I must say I reduce N the most. Timing is strain dependent. It's been basically found that Mg and K can be THC protagonist.....I use both in Mg/K sulfate form. those are reduced by 3/4's at the last 2 weeks....I have seen better THC levels when doing that.....I am now balancing Fe and Mn levels in my soils at around 100ppm. This is checked by testing and then building soils to match the results I shoot for. This is supposed to increase THC levels. The first experiments in this are just being harvested, so I don't know if this is working yet.

... First thing I have to ask is........How long are you curing for? I do 6 weeks minimum on a few strains but, 8 weeks is the average. Cure time and curing at 62% humidity is key to this (besides good nutrient use)...flavor thing!

I'm sorry but I have to run. Time to care for the garden and then I leave for a 4 day extended weekend I promised the wife...

I shall be back on Monday mourning to continue this conversation.

It's been basically found that Mg and K can be THC protagonist.....I use both in Mg/K sulfate form
I have to expound on this before I go! Later in bloom they are actually antagonist's! Why I reduce use at that time.
In late veg to mid bloom they increase trich production - thus THC content by volume = protagonist.

I say increase by experience, not some flashy add in a magazine.....

See ya'all on Monday.

You'll never quite get the yields from soil that you can from hydroponics no matter if you use nutes or not. This is mostly due to time; plants in hydro simply grow faster so the same yield requires less veg time than it would in soil. The difference is better quality & flavor of the bud so there is definitely a tradeoff. Yields indoors are mostly governed by wattage so you can get comparable yields in a dirt pot if you spend more time training and vegging even though it does take longer to get there.

I dont train or fuss. I top once maybe. I veg longer in pro mix to gain the same yields I enjoyed in hydro. Slow veg is often due to slow drain soil assuming all other areas addressed.
It is possible and easy with a little more veg time. Foliar feeding in veg ramps this up to near hydro veg rates too.

peace out

I already told you that these "PGR's" - have been either removed from these products that had them OR the products have been "discontinued" and removed from shelves. QUALITY sellers of nutrients, do not have any "old" products that contain these on their shelves!

This issue is MOOT!






The most toxic pgrs have been banned In USA for food consumable crops.and instead are used as pesticides. If your nutrient bottles are not for food consumable crops your in big danger!

synthetic PGR, that interferes with hormonal pathways is often regarded as a “Plant Growth Retardant”. Is not BANNED


the global PGR market is to surge from $3.5 Billion observed in 2014, to $6.4 Billion by 2020.



Evidence for PGRs’ being dangerous
The verdict on whether PGRs are dangerous to human health continues to remain open for discussion. With differences in testing, regulations and laws across the world, PGRs are deemed as both safe in some countries and toxic in others. In the USA and Europe they are largely regarded as pesticides, though still widely used in agriculture.

The PGRs that interfere with hormonal pathways (in particular Gibberellin) and their biosynthesis are seen to be the most dangerous.

Potential threat to human health
When considering the use of Cannabis from a medical perspective it would be best to avoid Cannabis grown with synthetic PGRs where possible. Although there are many PGRs out there, here is an outline of some popular synthetic PGR Gibberellin inhibitors:


An overview of the evidence out there for the dangers of PGRs has a strong case with studies showing synthetic pathway inhibitor PGRs in particular to be carcinogenic , toxic to the liver and cause infertility to name a few.

These effects were observed in mammalian studies. The level of exposure to PGRs in these trials however is likely to be much higher than the levels of residual PGRs found in crops. It may take large unrealistic amounts of PGRs remaining in or on the final product to have significant health hazards. It is also worth noting that for every study supporting the dangers of PGRs there is another showing them to have little negative affects on mammalian health.

As a consumer who isn’t strict with maintaining a healthy diet in general you could argue that the consumption of PGR grown cannabis is no different to eating a meal from your local takeaway or fast-food joint. Perhaps more worrying for Brits, despite being prohibited in many countries, Paclobutrazol is still licensed for use on apple, cherry, pear and plum trees in the U.K. With that in mind your PGR joint and local supermarket apples are both as potentially toxic to you…
