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

Pretty sure it's not root aphids. The plants I have in veg that are being feed AN are nice and green. They don't turn yellow until I switch to Jacks.
I experienced a similar problem. For some time I have been following this topic, looking for new information that can help me.
I have two growing rooms in similar settings, but in different places.
in one environment the use of jacks is perpetuated. I have been making adjustments for each strain, I have achieved good results by cutting the calnit after the fourth week, and including a calcium + boron fertilizer.
the mystery is that in another place, using exactly the right proportions the cycle does not develop well.
the plants remain slaughtered, regardless of the effort to correct the problem.
I already ran several cycles with jacks and calnit without problems in one of the environments, while in the other nothing works.
several deficiencies arise.
I've already lost almost three cycles in this space, and I find it curious how the jacks can work so well in one place and terribly in another.
I am not an expert, but I have some experience in gardening, and honestly the challenge in this matter has taken my nights off. :conforto:

Interesting indeed.
For myself, to me my plants just look as though they are lacking nitrogen big time(especially in weeks 1-4). They appear a little better in the final weeks of flower but I assume that's due to not needing as much nitrogen anymore. I'm really quite interested in what results I'm going to achieve this week with the addition of GH Cal/mag. Even though it doesn't make sense I can't help but feeling this is going to be the key addition that I'm missing. Although I could be wrong though. Stay tuned all.

Botanicare cal-mag is a nice addition to the jacks hydro/calci-nit combo. But low dosage, like .5ml per gallon. Im always suspicious of the powder weight being different depending on moisture in the air. These chemicals are super concentrated and can pull moisture out of the air, so mixing nutes by weight isn't always as accurate as mixing nutes by ppm.

Thx for info. I currently already have a bottle of GH cal/mag so I'm going to try that first. If it works out I'll check into the Botanicare stuff.

gh stuff is basically the same. I didnt realize you mention a brand. but yeah should be more or less the same results.

I hear ya Sam, I think that's been somewhat standard in this thread.
However for myself that exact recipe has been a recipe of disaster for some reason. It's nitrogen related, I'm sure. Just not sure of the solution yet.

The four words why I'm even here tbh.
Rabbi I'm growing in rw I wouldn't think aero would be much different.
I actually have the opposite problem of having too much nitrogen with very dark green leaves.
Only thing I can think of is your pH could be off. Maybe your pH meter is messed up? like I said b4 AN nutes you don't have to worry about pH as much unlike the jacks.

I have never had any nitrogen issues using Jacks. Like the poster above me said, they can be a little too green sometimes. The beauty of the system is you can add more calcnit or take some out when you mix them up. I am banking on you having a PH problem.

Have you checked your runoff again?

something other than the brand of nutrient is your cause for problems. too many other variables to say for sure what is causing the problems, but nutes are surely not the problem as you have exhausted most variables there at this point. Maybe the plants are just shocked from being fed so many differing nute profiles and are stressed out under big lights. As others have asked, could ph still be in question? or bugs, temp swings when you arent around, other environmental issues, etc etc.

Checked my ph tonight and it is indeed a little high. I really don't think ph is the issue here though but who knows, I could be wrong.
Anyway mixed up some new stock solution tonight and going to give em a fresh rez/nutes tomorrow with some cal/mag. I know you guys don't think the cal/mag will help but I need to try this to satisfy my own curiosity. They just look like they're screaming for nitrogen.
As always I'll keep you all posted.

But then why does jacks work in the other location and not the one in question?
