So, seemingly sudden drop in the health of plant #1. She was bigger than plant #2, but now she's looking dreadful. Lots of spotting and leaf curling. There's some of that on the health(ier) one, but not near as much and it seems to be healing -- and growing!
I topped plant #1 because I knew it was risky, but wanted to see what would happen and took a chance with a plant that was already looking a bit unhealthy. From what I can tell, I would definitely believe that it is burn considering that my 1000w LED was just 16 indes away from them for 8 days, since sprouting. I moved em up to 48 inches on day 9 and plant #2 reacted well but plant #1 is only getting worse. It could also be a PH issue, causing a calcium deficiency, but I've been giving them 6.0-6.5 PH treated water for 4 days now...
I want to do LST on the health(ier) one, but not sure if it's too early. What do y'all think based on the stem growth?
