Ok so the big plant is under a 600 watt vivaspectra I’m guessing full spectrum whatever the flowering light is. It is 1 week into flower. I gave it some tea that I had brewing for 48 hours a couple weeks ago which I heard could be part of the problem. Worm castings, 444, great white, a couple drops of molasses, and maybe a sprinkle of recharge. I live in Alaska right now temps in flower closet float in the 70s and humidity from 50-55rh. I need to invest in a ph pen I’m working on that but I believe our city water is decent hard to find good reports online. The smaller girl was a clone I got from a dispensary and recently transplanted in a potting soil coco coir mix with worm castings then I notice the lower leaves are starting to brown and crisp. I will post better pictures and descriptions in morning.
