What is the temp and humidity in the grow space? How often and how much water/nutes? Usually curling up of leaves is some kind of environmental reaction. Plant may be having a problem transpiring or something. Give us some more info and pics if you can, everything else will just be a blind stab.
irydyum Reviewed by irydyum on . What's wrong with my plant? Leaf edges curling in... This is my first grow. I have one plant under 2x 100w CFLs. It's about 3 weeks old now and I've noticed that the edges of the leaves are curling up and in towards the center of the leaf. I don't know if this is relevant, but there also seems to be some white-ish powder looking stuff on the new leaves. If anyone could give me some tips I'd really appreciate it. I'll post pics as soon as I can. Thanks! Rating: 5
