im in need of some help, im still relatively new to this been through one harvest. I belive my plants have some sort of deficiency, i just started flowering a few days ago im growing under a 400w hps in a 4x4 tent, temps are between 75-80 with 60% humidity, im using jack all purpose, and just gave them cal mag yesterday. my ph is around 6.3 and nutes tested at 900 ppm. any ideas on what it could be if not magnesium?
How much Jacks did you use to achieve 900ppm?

It looks like you may be feeding them a little hot. 900 ppm might be a bit much for those younginz. What kind of soil and hot long since your last transplant?

I'm using sunshine mix #4, transplanted a little over two weeks since transplant, I was feeding them a little over 1/2 per gallon. It only happened on half of my plants.

:leaf:Oh yeah, I was getting to the point after all! Sometimes, the less you know, the more open you are to experimentation. Every great discovery has started with experimenting( we all "discovered" pot by experimenting with it! Who's to say my mélange of lights won't turn out to be a primo combo! I have or will have when all is here:
Side Lights;
1- 125W CFL 6500K- for veg., to be switched out at Flowering with...
1- 125W CFL 2700K- for flowering/budding.
1- 225 Light LED blue/white/red/orange spectrum

OVERHEAD: Always on:
1- 250W HPS with standard base
1- 42W CFL 6500K
1- 42W CFL 2700K
OVERHEAD Switched out by stage:
1 PAR38 14W All Blue LED for Veg.
1 PAR38 14W All Red LED for Flower/Budding

All this for about $180.

how the hell do you get all that for $180? I don't see 225 LED systems for that cheap..

Hey Riddle, whats your personal recommendation on the Dyna-Gro line? Would the High N pro 10-5-5 for Veg and the Bloom 3-12-6 suffice? Would you recommend any other additives?

But still bro 900 ppm ? We dont use ppm measurements . Start off 1/4 tsp and step it up gradually . I believe 2tsp is the most I've heard of but u cant slam a plant with that much all the sudden got to build up to it .

I used ppm measurements with my first grow with Peters. I tracked the water going in as well as my runoffs coming out. My tap water is about 170 ppm and when I add 1/4 tsp per gallon I end up around 350 ppm if I recall. I copied this from another place within the forum and it proved to be fairly accurate. If you prefer to monitor your feedings based on ppm this might help you. I definitely found it helpful knowing exactly what ppms i was putting in. Having said that, 900 ppm seems extremely high for 1/2 teaspoon per gallon. What is your water ppm and what measuring device are you using to measure your nutes? It sounds like you have ridiculously hard water or you're measuring a little heavy. Either way I would back off the nutes.

Copied from another thread in this forum:

[FONT=&quot]In the following example, Peters 20-20-20 is 728.3 ppm NPK. Add this to your water pps and you have the total pps. With most water soluble ferts if you follow the instructions for your particular brand you will be in a good range of tds for optimum growth with either the veg formulas or the bloom formulas.[/FONT][FONT=&quot]




One can estimate the parts per million in solution (ppm) produced by a quantity of fertilizer in a gallon of water, based on the fertilizer's N-P-K rating.

For each number in the rating apply the following formula:

> one teaspoon (5ml) of a given fertilizer in a gallon of water
(10xN)÷ 0.768 = ppm

> one tablespoon (15ml) of fertilizer in a gallon of water:

(10xN)÷ 0.256 = ppm


Example: Peter's Professional All-Purpose Fertilizer with N-P-K rating of 20-20-20.

(10x20)÷.768=260.4 ppm

Therefore, one teaspoon (5ml) of Peter's Professional All-Purpose 20-20-20 in one gallon of water will produce a solution that contains approximately 260.4 ppm of Nitrogen, 260.4 ppm of P (P2O5), and 260.4 ppm of K (K2O) for a TOTAL ppm of approximately 781.3 . [/FONT]

Hello Riddleme,

I noticed your thread which caught my eye.
As a new grower I was torn as to which nutes to use.
While budget is a big factor I didn't want to use crap either.
It seems that Jack's is pretty well balanced making it a simpler choice.
While you mentioned that the 8oz tubs were only $4.99, they charged roughly 10 bucks for shipping. With that rate I figured I would go with the 4lb tub. I bought the DUO and got the classic and bloom. I figured maybe this way I can sell half and pay less than I would if I bought the 1.5lb .

I'm roughly on the 4th week. I fertilzed last week using an organic 4-5-3 mix. I will now start the Jack's regimine and see how it goes. I thought it might work better since you don't have to wait for the food to break down like the organics and Jack's would be a faster direct feed.

I believe the recommendation was to use 1/4 tablespoon at first and then move to 1/2 tablespoon feeding every other week. I then assume I use the classic all the way up until flowering and then switch to the bloom. After that stop all fertilizers about 2 weeks before harvest and flush with plain water. Does this about sum it up?
Are there any other trace elements that I need to add?

Thanks for your help.

Been trying to spread the word as much as possible
These are REALLY GREAT NUTES !!
the 8oz tubs are only $4.99 each

you can type in your zip to find a dealer near you

PS I learned about these nutes from Uncle Ben, just one more gem of info on this forum

I believe it's Teaspoon, not Tablespoon

These sound like a good alternative. All about cost efficiency....I may try them if I can't figure out if what I have is ok. Does anyone have a chart they can post or a link to that describes in detail what PERCENTAGES of each nute is ideal? I can't seem to find one. Yes, I know there is a mathmatical formula that allows you to calculate what is in the fert you're using but I'm bad at math and frankly don't feel like doing algebraic expressions in the middle of my local garden supply. Fertilizers are labeled by NPK and then broken down by percentages. I am worried that eventhough my NPK is ideal, the actual amount of each nute is off. Im showing signs of either magnesium or nitrogen defiency so those numbers would be helpful if anyone just has those. The last thing I want to do is go and add more if I'm wrong about the problem. Thanks in advance....

Depending on your medium and soil amendments you will probably still need to feed with calmag during flower. Either that or other organic additives. I know I do with FFOF and I start the feeding immediately at the start of flowering throughout until harvest.

Thanks very much shwagbag. Didn't think to look at jacks. seems obvious now. think my brain was fried. Nice ass btw :mrgreen:

Re the comment about all "medical" Cannabis should be Organic.

First, what is the definition of "organic"?

I've been using chemical nutes in soluble and granular forulas for about 15 years, since a year long discussion with a well known Horticulturist in the Northeast. He made it clear that nutrients that plants can uptake aren't toxic at normal levels.

"Organic" isn't so much about nutrients, but refers to the practice of avoiding toxic herbicides and pesticides.

I've never purchased "specially formulated" nutes for Cannabis, or anything else.

I buy whatever is cheap and blend my own nutes, based on the NPK in each product.

Generally I shoot for a ratio of 2-1-1 in veg and 1-4-3 for bloom.

Paying more than $1 a pound for nutrients is something I avoid. Sometimes, you can get good nutes for a fifth of that.

Just my $.02.
