Didn’t want to start a whole other thread just to ask this, but what about sulfur? How high can I run S without burning anything? If I run Mg in late bloom at 60, can I safely run S at around 80-80?
That is good to know. I’m currently at 90. Just got a bunch of raw salts, so let the fun begin lol!I strive for 100ppm of S, but I accept as low as 50. The greater the S content, the sweeter the smoke.
I wish I could translate all this hydro talk to soil. I wonder what a ppm is..
The two should join forces once and for all
Wouldn’t a plant still follow the same general nutritional trajectory regardless of antagonisms? Within reason, of course. This is assuming your feed fairly balanced.One of the fundamental problems in using tissue samples to establish a plant's nutrition demands is the fact that the test-plants' nutrition regime itself influences the outcome.
Matters get worse from ion rivalry & how it all works out together, so it's impossible to just alter a single parameter without influencing another, or more.
Hello, this study on Cannabis deficiencies & toxicities elaborates on that topic in its preliminairy paragraphs.Wouldn’t a plant still follow the same general nutritional trajectory regardless of antagonisms? Within reason, of course. This is assuming your feed fairly balanced.
Would love to hear more about this stuff.

They also did test on Bor-toxicity so I'm having my doubts if that "Dr" (previous poster in this discussion) did grow Cannabis healthily with absurd high dosages of 8-10ppm[!!!].
That would render Bor actually a macro-mineral. The study did simply increase Bor by 1 order of magnitude.
Bor is generally known for its narrow tolerance for plants.
I also cannot find that N has the ability to lockout B, because B is mostly taken in in a non-ionic state and simply because it's a micro-essential that already is taken in by 3 orders of magnitude less. An increase/decease of N by +-50% will not do away with this large discrepancy....
Ion rivalry is based on the strength of the electro-chemical charge an ion exerts and how big it's molecule volume incl. its hydrate hull is in relation to the other kat- or anions.
Plants can regulate some of that via ion pumps channels etc but at the end of the day they have to deal with whatever nute recipe makes it in.

care to share your mix or target ppms for veg and flower?Jack's has too much B and not enough Ca, especially for Kush strains. Most of the micros are not well dialed in for cannabis and the total inability to change any of it is itself a weakness. By acquiring the same exact stuff that Jack's, or every other branded nutrient on the market today, is made of, and keeping it all separate, you cut out all of the middlemen and science that aims to please all crops instead of just cannabis. I have my every element right where I want it, I pay less than Jack's for it and I do not have to worry about my PH either as that's baked into my own recipe.
