Hey, so this is my first attempt at trying to keep some plants indoor in an attempt to get some clones. I've got a White Widow and Chocolope 1 and 2 months old respectively. I got them as clones in a cup, and transplanted them into slightly bigger pots that I filled with a Fox Farms Ocean Forest/Perlite mix. Ive had them inside a cabinet with 4-6 100W equivalent Ecobulb Plus Daylight CFLs. Recently I started seeing the leaves (particularly on the Chocolope) start to curl down and crispy brown on the edges. Nute burn, light burn, or heat stress? I've attached pictures of the Chocolope, as that seems to be doing the worst, but spots on the Widow can be seen in the picture with both plants.
Looks like this guy prob found the answer (post is old) but to others looking, looks like this is from nutrient burn.
