Pro Grow - Autos

Almost no change in height so these may be finished growing vertically. A lot of lower fan leaves have been turning yellow and some have been covering up buds from the light, so I've been plucking those off almost daily. I bumped the grow light up to MAX intensity. Unfortunately it has been heating up the grow tent a little, but only to a maximum temperature of about 82F and only when the light is on. The upper leaves on Bruce Banner are thinner than the others, and I don't know whether that's because of my LST'ing or because it is a sativa-dominant strain. Maybe a little of both? The last Bruce Banner that I grew re-vegged due to a lighting change, so I don't really have another healthy one to compare it to. The humidity hasn't gotten higher than about 60% this week, although I bought a dehumidifier and put it right outside the tent since the summer months typically bring a lot of rain and I'll need it more for then than now, but nice to have now if I can get it to bring the humidity down from about 60 (or higher) to about 50 when necessary. *** 4/15/23 EDIT *** Now it seems lower leaves are yellowing at a somewhat alarming rate, SO I've ordered a pH testing pen, pH Up, and pH Down to find out what pH my watering solution has been in case it has been too high or too low and I need to adjust it. ETA is about a week, although hopefully Amazon sends it sooner. If there IS a pH problem, it's a good thing that these are weeds after all, and autoflowers tend to be more forgiving! Also I tried putting the dehumidifier INSIDE the tent, and noticed today that the basil plant nearest to it looks incredibly "drained". Also, Bruce Banner's leaves are incredibly "droopy" now, almost ALL of them, so I'm wondering whether the dehumidifier was actually sucking the humidity out of my plants instead of the air, and I put it back OUTSIDE the grow tent to be safe, and gave the plants a little extra water.
