Hey
By what you said, you fed them already..You shouldn't have to feed for 5 or 6 weeks..at that point you use a 10-60-10 for flower stage..your Miricle grow should have low numbers like 3-4-6 or 4-5-6 something like that..you food should be at 20-20-20 if needed..you should't need it though..I do believe that you way over fed them..roots won't strive to go to the bottom when there is nutes at the top. an when it's to much it will kill them..try useing just the soil an the nutes it has in it already..don't feed for a while..see if that get's you better results..also tell us a little bit about your lighting system?? hope this helps ya out..stay cool & grow big budz..
