Ok, so 4/5 of my plants’ have a soil pH range of 6.8-7.2. The one with lime green leaves, burnt tips, and curling read 6.81. Using a high quality Hanna meter freshly calibrated. Interestingly, the last plant had a soil pH of 7.8, but it looks healthy. Pictures attached.
So I’m guessing they’re just getting hungry. It does kind of look like nitrogen deficiency. But we are half way through flower, so I wouldn’t think to feed them N.
i can feed them subcool super soil by top dressing; that should give them a bit of everything. I also have a bag of FF Tomato and Veggie (5-7-3) and cavern culture (1-12-0). Don’t think the CC would do them any good, as they don’t look all that P deficient.
just kicking around ideas. Thoughts?
