how old is the plant? i'm asking this as if it's old and wasn't getting any nutes it would strat using what's stored in the leaves...... it could also be a Potassium (K) defficency, looks like that as well....... it also looks like nute burn, maybe from accidently spashing it on the leaves? also try to lower the temp a little bit, as long as it isn't allways in the higher 80's, better to be 70-80........Peace out.......Sid http://www.overgrow.com/growfaq/?qa=1111 try this link, it may help you more
Clone is about 3 1/2 weeks old. first feeding was three days ago now. 20-20-20 diluted to 1/4 of what directions said. also with 1 tbsp. of epsom salt per gallon. we thought it might be mg. deficiency. here's another pic leaves curling.
