So I'm having some problems, first grow. FFOF soil, AN nutes (grow/micro/flower), 600w dualarc bulb, 3x3 footprint, unmanaged but fairly consistent high 70-low 80 temps, unsure of humidity, but I imagine it's sufficiently high for veg.
I saw some clawing on my 3 plants (one in 5gal, 1 has a liter of soil or so, the other maybe twice that), all growing for 10 weeks or so, and the smaller two will be transplanted tonight. The clawing occurred for maybe two days, just on the end sections of the leaves for two plants, and an inverse canoe-effect for the fan-leaves of the third (which is the only sativa-dom of the 3). After those two days, the lower leaves of all 3 plants have started to wilt and have become excessively yellow like they are no-longer creating chlorophyll (is this correct? not like a mag def, but consistently yellow all over the leaves, only on the lowest branches). The yellow has occurred for two days now, and the clawing stopped with the onset of the yellowing....also, the other leaves (further up on each plant, still a healthy green) have been drooping since the clawing left and the yellowing started.
I've been watering with 6.2-6.5ish water...it's certainly possible that I have been underwatering, but the one in the 5 gal was watered 4-5 days ago, just before the onset of clawing. I imagine that I should just use a heavier concentration of the micro (Nitrogen-heavy AN nute) and see if it truly is a N-def?
Does anyone know if the micro Advanced Nutrient solution is safe for foliar feeding, and at what concentration? (had been doing normal watering at about 6ml/gal, with a planned step-up to 8ml/gal for the next watering).
Thanks for any assistance.
