I have a few plants and a while back one of them got burned some type of way but I didn't care as much because the plant was deformed looking anyway, buy now another one of my plants started to burn. When I first noticed it it wasnt as bad, but today when I went to look at it the plant was burned. Another thing I noticed was the leaves were starting to curl under kinda, why is that? I'm using (2) 23 CFL 1600 lumens each 5000k ------ (2) 18w CFLs 1100 lumens each 2700k Light cycle 18/6 P.S. I know you guys are gonna say I need more light but I broke 2 of my cfl bulbs screwing them in.......
What is your soil mix? They look fine to me, the little spots could be splashed nutes or maybe a little leaf burn from water droplets magnifying light intensity. More info though! 135w UFO LED Micro Grow: http://forum.grasscity.com/index.php?/topic/1308910-135W-Led--Organic-1St-Grow
They could well be root bound, also clear cups not good for roots Sent from my SM-G900F using Grasscity Forum mobile app
