A question for the growers using Jacks 5-12-26

[Rabbi]

Not sure if that question is for me or not but just to clarify, for myself Jacks hasn't worked in either veg or flower. I'm currently using AN for veg because all my plants went yellow when I used Jacks. After I switched back to AN they were all green again in about a week or so.


Edit: Never mind. Question was obviously not for me lol. Carry on.

That's the question I've been trying to answer.
I do not speak English, I fear not being understood, and therefore I did not extend myself in the information.
cultivation for 10 years perpetually. I have already used lucas formula with flora series, maxibloom, jacks, and plant prod that is similar to jacks.
in one of the spaces everything works independently of the fertilizer. In the other, maxibloom works, but jacks and pp do not work.
the runoff is adequate, I spent 2017 trying to adjust the cycle with jacks in that new space without success.
The stakes come with jacks in .67 or 1/1 satisfactorily, but whenever they go to hps they end up packing in this transition. (fluor / hps 18-6 / 12-12).
I already tried 321 jacks, already tried starting from 600ppm, 800ppm, 900ppm and nothing.
The room temperature controlled at 22(c) degrees, cultivating dtw sog coconut plants in 2 gal pots.
everything works in one place and nothing works in the other.
I am not superstitious, but I confess that I have almost given up on logic in this matter.

Can you explain a bit more? I understand that you're having issues at one site and not the other in what seem to be identical conditions, but I don't understand what 'packing' is or what the specific issue is at the troublesome site.

Thanks!

I see alot of grows where ppl veg under fluorescent or low wattage MH. Than throw them into flower and blast them with high watts HPS without raising the hoods high enough to let the plants adjust they get stressed and show lots of defs.

Could this be the case with the other grow location where your ceilings aren't as high?
Or you need more air flow to keep things cooler?
Are plants in the other location drying out faster or slower?
I would start the process of elimination in matching every condition with each locations environment.

OK.
The plants yellow, the main shoots, and lose leaves also in the lower shoots. It looks hungry, but it is not. It sounds ph, but it is not. It looks like root problems, but it definitely is not. As I mentioned all the variables of circulation, humidity, and temperature have already been corrected, increased, decreased, ie in the new location maxibloom works but not jacks.

The funny thing is just that.
In my house I have cultivated jacks several times successfully. I even have an excess of green with use of 321, so I always have to cut the calnit and complement with calboron.
It happens that in the new room I spent the last year trying to hit the hand, I reviewed all the parameters, relearning several things, but simply jacks over there does not work.
I believe it is the water, but as the places are close it is difficult to say.

Occurs on all plants, they are killed every time the photoperiod is changed.
I imagine that when they come out of the fluorescents and go to hps, they stress, but I've done it many times successfully in other places.

So after giving the Jacks a try with the cal/mag the results are:...New plants turning yellow, old plants still yellow as fuck and producing nothing for buds.

Hate to say it but I'm done with Jacks guys. I gave it an honest try as I really wanted it to work out for me but bottom line is that it doesn't for whatever reason. Hate to say these words even more but I'm going back to AN. I know they're a massive rip off but what it comes down to is that they work for me and the Jacks doesn't unfortunately.

Thanks to everyone here who tried to help me. Even though things didn't work out, I truly appreciate the effort. Later gang.

Just out of curiosity, are you mixing and adding each part to the rez separately? You aren't mixing CalNit and the 5-12-26 together, are you?

lol no. I add the 15-12-26 first to the desired ppm. Than I add cal/nit to the desired total ppm. 360 hydro, 240 cal/nit if I'm aiming for 600.

 

[Rabbi]

Run veg bloom if ya wanna avoid an, not as cheap as jacks but easier with solid results

Sorry for my ignorance but what's "veg bloom"? It's not that I completely hate AN but would rather find a solid dry nutrient company. It's no secret here that the water based nutes are complete rip offs compared to the dry ones.

Have you tried just bumping up the calnit?

 

[beta]

lol no. I add the 15-12-26 first to the desired ppm. Than I add cal/nit to the desired total ppm. 360 hydro, 240 cal/nit if I'm aiming for 600.

How many grams per gallon does that work out to?

 

[Rabbi]

Have you tried just bumping up the calnit?

Yes. At one point I tried the Hydro at 400ppm and the cal/nit at 400ppm for a total of 800ppm. The yellowing issues remained the same.

Ahh, I see. Thx, I'll eventually look into them after I recover for a while first.

 

[Rabbi]

Not quite sure tbh. I've been making stock solutions with this formula: "880 grams per gallon of Hydro(in one bottle) and 580 grams per gallon of the Calcium Nitrate(in another bottle)". Than I add/mix them in my rez(seperately), mixing the hydro first to my desired ppm and than I add the cal/nit to the total ppm. My ph is 6.0. My tds meter is brand new and calibrated.

Before you give up I'd just try 3g Jack's Hydro, 2g Jack's Cal-Nit, and 1g Epsom Salt per gallon of water. Don't PPM it, just pH it and feed. Skip the stock solution, just mix it fresh. Give that a few days and I feel confident your problems will turn around.

If your water starts out at a high EC you probably aren't adding that much Jack's when doing it by PPM

I've done the 3-2-1 as well. Although I have been mixing from stock solution I just really have a hard time believing mixing it straight from powder will make that much of a difference. When I mix for ppm levels it's only the nutrients ppm I'm counting, not the waters. Pretty sure I'm doing everything right. I'm as stumped as you guys tbh.

Just try mixing it from powder. I've heard other people say they had issues w/ stock solutions as well. Powder, 3-2-1. I bet it'll work.

Hmm, I might consider it someday maybe. Right now I feel as though I can't afford to waste another week and need to go back to something I know for sure works for me.

I don't blame you bro. It's taking me a while to line out my Jacks use as well. My circumstances are different but it wasn't as simple as 321 I had other issues going on... salt buildup causing lockout, res temps in the 50s causing lockout, etc...
