Check this out... http://boards.cannabis.com/grow-faqs...mping-off.html ...just a thought, however it appears that whatever it is, only the first set of fan leaves are affected...with only 2 fluorescents your temps should not be too high...

I have had similar looking problems before and they have always recovered, I would just keep an eye on them, don't water them till the soil dries out, keep an eye on the new growth, if it looks healthy you're good, (the affected leaves may get worse, and dry out).

Good luck!
midlifecrisis Reviewed by midlifecrisis on . This plant doesnt look healthy? What can i do? Ok, I have not used fertilizer and indications suggest having too much nitrogen in my soil...dark green leaves and leaves curling upwards. Take a look at my pics, could any1 tell me what I can do to improve them? Do they need flushing? Thanks Rating: 5
