It's my first attempt at hydro. Using 5gal buckets, top-feed drip system, 1 air stone in each bucket. Noticed this issue in the past week or so, starting at the bottom and slowly moving upward. It's a Blue Dream plant (Garden of Green) and it's roughly half-way through flowering. Feed is at 1100ppm, 70% MegaCrop and the rest is DynaGro Bloom and/or MagPro, with a little epsom salt and Southern Ag fungicide. I've been setting pH at 6 and letting it drift up to 6.5 before adjusting. If I put it below 6, it just seems to want to keep drifting downward. Temps max out in the upper 70s, humidity probably a little higher than I'd like in the 60s. 480watt Kingbrite QB, 3500K with some supplemental UV and IR diodes.
Not sure what to make of the leaf issue on the one plant. Not really getting any burnt tips or yellowing, just leaves kinda randomly curling down and shriveling, with some purple/red streaks on stems. The plant doesn't seem overly green to me, but maybe N toxicity? Just in case, I'm gonna mix much less MC into my next res change, going higher on Bloom nutes to see if that makes a difference. Also too inexperienced to know how worried I should be about the pretty drastic difference in bud development between the 2 plants. While the Blue Dream was stretching like crazy, the White Widow seemed content to just stay short and start putting on some mass. Operator error, genetic quirk? Comments, thoughts?
Hopefully, this video and some still pics are good enough to show what I'm talking about:
