In relation to Boron specifically. Why are people even still discussing this? Oh yeah... Forum sponsorships got pot growers so fucking confused, even the few sane members start to doubt reality after hearing the same backwards shit for years on end.
There's a myth that nitrogen toxicity is common and boron deficiency is rare in Cannabis. Total bullshit! Nooone has ever seen nitrogen toxicity in Cannabis. Calcium single handedly causes every problem in Cannabis, from genetic drift to mold. Easy to fix. Add boron. Check PK. Stop letting people tell you it's a mutation or you need new lights or ph meters or to dim your lights. Don't end up another loser being laughed at, thinking youre hot shit posting boron deficient photos all over the global web like a bafoon. Just add fucking boron. It's not cool to be a poser anymore. Fix your shit.
I agree on the N tox 110% too. What I always thought was N tox was an overabundance of Mg in my case (or maybe lack of P for the amount of Mg I put in as I had almost blue black leaves??). After i added a bunch of epsom to some tester plants thst were showing variagation, within about 3 days I had to tell myself "why does that look like serious N tox when I didn't add any N???" Mg and S stimulate N which was on my mind, but this was over the top coloring. They looked so dark they looked unhealthy.
A lot of us have been misdiagnosing our plants for years. I can admit it. Lots of bad info online, I've definitely regurgitated some of it before. What is your opinion on upper limits for Ca for a typical nutrient mix? Or is there no limit with enough B and it's cohorts? Right now I'm only playing with prepackaged micros and not individual salts. Finding a true Ca balance in coco is interesting. I wanted to play with B specifically but like you said we're hanging onto old data thinking its insanely toxic. The information I've seen online suggests over a 10 fold increase compared to what we're doing now.
edit: that B symptom photo with the corky stem is accurate for sure. That's a good visual que. And I feel like it's almost the first one fhat will show IME. Instead of adding B I dropped Ca, wondering if I should go back and try just B and leave Ca high. My only concern was comparing my B numbers to known good nutrient lines I've used, mine already seem high based on internet lore
Edit 6/3: well I seem to slowly be disagreeing with my old posts. I am running quite high calcium now with not much change to my boron levels (<.6ppm). Seems most of my improvement came from lower iron, higher mn, muuuch low K and much higher P. Live and learn.
