These just started barely flowering! They grew in height from about 10 inches to an average of 14 inches, although one is about an inch or two taller than the other now. Lower fan leaves are starting to turn yellow, which is exactly what happened this week of my other grow, so similarly I'll probably start giving these light nutes soon. 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 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 *** It seems lower leaves, particularly on my other plants that are about 2 weeks ahead of these, 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 that's closest to it looks incredibly "drained". 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.
