imgur: the simple image sharer Hey all. These plants are dying fast. All are light, light green to yellow and have lost all lower vegetation (yellowed and died.) General Organics - BioThrive Grow and Bloom Ph - around 6.3 Air not enclosed, just pushed around a basement. Temps are between 77 and 64F. Humidity is rock steady around 40%. I'm thinking either the Ph meter is way off, or they are seriously deficient. Some soil was re-used to fill in the bottom of the SmartPots, maybe the bottom 1/2 of their soil is old, but nutes were added liberally to make up for it. Any guesses?
I looked through some other posts here in GC. I'm thinking maybe nute burn? Especially since you said you were using liberally. Maybe too much of a good thing? How are you testing the ph?
Another pic tomorrow. The Ph Meter is a calibrated Hannah Ph/EC/PPM meter. Not sure if you have to calibrate the EC, and it gives wild readings between 1000 and 2000 little greek u's, whatever that means. They've been flowering a month. They were just watered with tap water 5ml BioThrive Grow 5ml BioThrive Bloom 1ml BioWeed 1ml Thrive Alive Adjusted Ph to 6.5
imgur: the simple image sharer Here are a few more with the HPS turned off. For some perspective they have all lost their biggest branches to a steady yellowing/browning. Some have spots or perma-wilt, but mainly the fear is the yellow leaves with necrosis-tips. Yellow lower leaves = N Def. however, Necrotic tips = over fert? That's the confusion. The air flow is decent, and the Ph is between 6 and 7 always. By the way I truly love you guys so very much. If you get a chance, check out Reddit.com/trees.
