Reverse Engineering everyone's nutrients

So, I've been lurking here for a while. I've used lots of different types of nutrients. And this thread is NOT a discussion of what nutrients are the best or what to use when or anything of the sort. I'll be honest, I mix my own blends according to very specific values and base all additions based on current water quality, not because I am following some calculator.

This thread is simply one thing: a reverse engineering of major brands of nutrients. That is, I break down a nutrient blend into the fertilizers they are made from.

What's the benefit of doing this? Well, it can save you a fucking lot of money if you buy 50lb bags or what ever from a local fertilizer retailer and measure it all out yourself. I will not tell you any specific retailers because I'm not here to advertise for a fertilizer retailer. Find someone local, that's all. It's not that hard. It might not be your local hydro store either.

Concentrations in miligrams per liter. (mg/l) That is, this is the amount of fertilizer you should add to a liter of RO water when you make it yourself. This allows you to use the same formulations you have always been using, but makes it less expensive. All of the fertilizers need to be added to RO water and then used as you would normally use them.

When I list the guaranteed analysis of a fertilizer or nutrient blend, the percentages typically have an accuracy of +/-0.05% or so for the macro nutrients and +/-0.0005% for the micronutrients. This means there is wiggle room with what what I show as equivalent. In addition, the guaranteed analysis of a blend lists a number of the fertilizers it is derived from. These are not always needed when reverse engineering them.

To measure these out you need a precision balance for the macronutrient fertilizers and you will need an analytical balance for the micronutrient fertilizers, the chelates. The precision balance will be used to measure out larger quantities of a fertilizer which is beneficial if you are making 5 or 10 gallons at a time. They tend to cost $400-800 and have an accuracy of +/- 0.1 to 0.5g. You can get ones that can read up to about 15,000g. The analytical balance costs $1200-5000 and is used for measuring <300g. Some have max masses of 200g. They tend to have accuracies of +/- 0.1mg(0.0001g) and are necessary for the smaller quantities of micronutrients as the amount you add might be actually smaller than the accuracy of the precision balance.

Cultured Solutions Veg A:

Veg A has a guaranteed analysis that is the following,:
N total: 5%
Nitrate-N, N-NO3: 4.6%
Ammoniacal-N, N-NH4: 0.4%
Urea-N, N-NH2: 0%
Phosphorous, P2O5: 0%
Potassium, K2O: 0.3%
Calcium, Ca: 6%
Magnesium, Mg: 0%

Boron, B: 0.015%
Manganese, Mn: 0.017%
Molybdenum, Mo: 0.001%
Zinc, Zn: 0.003%

Derived from:
Ammonium Calcium Nitrate
Potassium Nitrate
Iron EDTA
Copper EDTA
Manganese EDTA
Sodium Molybdate
Sodium Borate
Zinc EDTA

Here is what you need to get that:

Calcium Nitrate: 304,601 mg/l
Potassium Nitrate: 6483.4 mg/l
18% EDTA chelated Iron: 3,166.6 mg/l
18% chelated Manganese: 944.44 mg/l
15% chelated Boron: 1,000 mg/l
20% chelated Zinc: 150 mg/l
17% chelated Copper: 205.88 mg/l
8% chelated Molybdenum: 125 mg/l

This creates a blend that has the following percentages:
N total: 4.945%
Nitrate-N, N-NO3: 4.6%
Ammoniacal-N, N-NH4: 0.345%
Urea-N, N-NH2: 0%
Phosphorous, P2O5: 0%
Potassium, K2O: 0.3%

Boron, B: 0.015%
Manganese, Mn: 0.017%
Molybdenum, Mo: 0.001%
Zinc, Zn: 0.003%

Net cost when you buy and measure this out: about $5-10/gallon instead of ~$45 per gallon.

You'll notice I did not have any ammoniacal nitrogen sources, or it appear that way. I do not use specifically Ammonium Calcium Nitrate. This is because the Calcium Nitrate I used has a little bit of N-NH3 in it. It's the Haifa GG Calcium Nitrate. You can buy it from some local fertilizer re-salers.

I also did not use a sodium molybdate or borate and instead decided to use the chelates. I did this because I try to reduce the amount of sodium I use in my hydroponic solutions as it tends to be bad to have above 75ppm of sodium in solution. When growing in soil it is less of an issue.

EDTA is a type of chelate, Iron tends to come in lots of types and the type determines the availability within a ph range. Chelation describes a particular way that ions and molecules bind metal ions. It makes them available to the plants in ways that they otherwise might not be when in solution. To put it simply.

Net cost when you buy and measure this out: about $5-10/gallon instead of ~$45 per gallon.

I'll be back later to add the rest of Cultured Solutions. It's late, so I'll add the rest of their product line tomorrow or Saturday and I will continue to add nutrient blends from everyone else as I have time.

What I am not going to do is teach you chemistry so you can understand how I did all this. That would take way too long and I have no interest in teaching people chemistry.

...all that knowledge going though all that trouble.

Why not just listen to your plant's needs, and feed accordingly with your own mix, based on their needs? Is way you could introduce better, safer products, as well.

You just made baby jesus cry with this post. Hes trying to save a guy a couple bucks which is something most of us need to be thinking about with all the brutal spraying being done on commercial pot farms. Grow your own, do it on the cheap and stick it to the man! Merry x mas

To the op, a couple questions. Where are you finding these recipies? And i dont know if you know why, but ill ask you anyway for your opinion, why is there no calcium in some of these recipes since its like one of the two most common deficiencies? Is it because it needs to be in one part A or B and not the other?

I made a spreadsheet to see the results of multi-bottle "lineups" and recreating them with generic products. Is that similar to what you're doing?

When I looked at HydroBuddy before creating a spreadsheet, it didn't seem to have a way to unravel multi-bottle "lineups." It looked like it excels at telling you how to use those bottles to reach a desired formula, but not the other way around (i.e., what is produced by using those bottles at different proportions).

Maybe I didn't use it right(?). But, I agree, HB is impressive.

Contact the state dept of agriculture. Ask them what's in the bottles and they will tell you. 98% water. The rest chemicals that cause cancer, kidney disease, and eye issues. And respiratory disorders.

Probably not relevant to the OP's topic, but here are a couple links to lookup popular commercial fertilizer products:

Bravo! I applaud the OP's desire to educate the masses about the FACTS of plant nutrition.

Lesson #1: if it's in water bottle form, you paid too much.

Agricultural dry nutrient salts have all the pricing advantages and more of DIY nutrient mixing without the hassle of measuring out tiny amounts of micros. Premixed, yet still dry.

The money saved over waterbottle nutes is shocking. Why? Because those nutrient companies are RIPPING YOU OFF!

It turns out there is massive collusion going on at the hydro store distributorship level; the first thing a new store operator has to premise is that he will ONLY use an approved list of distributors, excluding all others. I believe this is illegal, but they've been getting away with it for over a decade.

There's only one reason why they'd do that; to support artificially high prices and offer the often uneducated customer an alternative narrative to the actual chemistry going on at the root level.

That's right; all that talk about calmag and boosters is bullshit. Straight out of their asses! Did you ever wonder why you have trouble sorting out nutrient problems? Is not you, it's the contractually obligated hydro store owner trying to sell you more bullshit.

That is what I do. As I mentioned, I take water samples and send them off to a lab for testing. This gives me a number for the exact amount of macro and micro nutrients that are being used. This allows me to make adjustments that are based in science and not guessing.

Fertilizer companies are required to list the guaranteed analysis and what the blend is derived from. You can get them from the company's website and they are on all the bottles.

The reason why calcium will be found in only one part of a two part blend and also the reason two part blends exist in the first place is to prevent calcium based precipitates from forming in the bottle. Example: Mixing Calcium Nitrate with a Magnesium Sulfate in the high concentrations of these blends will form a calcium sulfate precipitate. When you mix it into your water, it's a much much lower concentration, so it's not a problem.

The rest of the chemicals are fertilizers, hence why I listed them. The things you need to grow your plants faster and bigger than by just using the limited minerals added to your municipal water supply. A chemical compound is not dangerous because it's a chemical compound. Sodium chloride, a chemical compound, is safe to eat in small quantities. That is, fucking table salt. Dihydrogen Monoxide will kill you if you eat too much or don't eat any. That's because it's water.

The responsible and sometimes irresponsible use of chemicals is why the world is industrialized the way it is. No sense in spewing sensationalist bullshit about fertilizers that have been used responsibly by farmers for the last 100 years.

Phosporic acid is the most common preservative in fertilizers. The other 2 are either sulfuric acid or formic acid. All 3 not safe. Over time will cause disease when crops are consumed. Eating or smoking. Your body absorbs those harmful chemicals and can't purge them out so they build up and cause disease. There's several others too. Like ehylenediaminetetraacetic acid which is used as a chelating agents in most bottled nutes.

Phosphoric acid is known for causing skin cancer, eye disorders, kidney disease, and several respiratory and / or lung disorders. It's also in many processed foods and soda.

Nutrient adjustments based on actual data? Blasphemy! Lol

You know your shit well enough to make meaningful contributions to nutrient calculation software? Impostero!

Telling the obviously wrongheaded and terribly under educated that chemicals are not poisons? Apostasy!

Keep swinging that sledgehammer at the foundations of hydro store disinformation, brother- with enough of us chipping away at it, we'll bring the whole cathedral of lies down on their heads!

Phosporic acid is the most common preservative in fertilizers. The other 2 are either sulfuric acid or formic acid. All 3 not safe. Over time will cause disease when crops are consumed. Eating or smoking. Your body absorbs those harmful chemicals and can't purge them out so they build up and cause disease. There's several others too. Like ehylenediaminetetraacetic acid which is used as a chelating agents in most bottled nutes.

Phosphoric acid is known for causing skin cancer, eye disorders, kidney disease, and several respiratory and / or lung disorders. It's also in many processed foods and soda.

Thats why you don't drink them, dimwit. They're NUTRIENTS, meaning you feed them to your plants, who then convert these chemicals into other forms we desire.

If you're so terrified of chemistry, you should definitely not be smoking weed. Shit's just LOADED with chemicals like THC, CBD, CBM- and many more besides!

Bwahahaha! Idiot.

In future, if you'd like your opinions to be taken seriously on these matters or any others, EDUCATE yourself. That does not mean merely Googling shit one handed while smoking a bowl with the other.

Again when you eat fruits and veggies, eat edibles, smoke pot, your body absorbs those chemicals. Partly why I've done no till for the last 5 years.

Flushing doesn't get rid of chemicals That only removes salts.

Fertilizers are just as harmful as pesticides they have several of the same chemicals .

Read some books and university studies you might learn something you dimwit.

Funny how you argue half the posts I make and you don't know what you're talking about.

Thats because you're a completely ignorant hack when it comes to half the shit you say, silly boy.

Again, slower this time; the PLANT uses these nutrients to synthesize other compounds, which we in turn ingest. If you knew a damned thing about chemistry you'd never say the shit you did above.

Now go crack a textbook before you make yourself sound stupid again.

Look man, I'm not here to argue what will kill you in 3 days or what will kill you in 30 years. I'm just here to show everyone what's in the expensive nutrient blends we've all been buying. Take it somewhere else or start a new thread for it.

Lmao. There's so many studies that have shown what I'm talking about. Several from Oxford journals experimanta .botany dept. University of Missouri, Washington state, Boston University, etc.... Next time you talk out your ass. Make sure you know what your talking about. Your contradictive post made you look even more stupid.

I wasn't arguing. I was stating that you can get all the info from the dept of agriculture without reverse engineering. Nutrient companies are required by law to register their product and disclose everything to the dept of agriculture in each state.


Youre the one who said don't spew sensationalist bullshit when in reality what i said is all fact

You're right, I can contact the dept of ag.

What they are required to disclose to the dept of ag is a guaranteed analysis, which shows concentrations of each element. It DOES NOT show what salts are used to create it or the concentrations of those salts. That's what I'm showing everyone here. How to make the same product from its base constituents. All of which are common and available prilled or powdered fertilizers.
