Today, second day of flowering as well as the second 12hours of my 4 CFLs shining onto my ladies, I've discovered they've been over heated. Since I run the lights while I'm asleep I did not get a chance to check up on my ladies until I woke up.
I changed from 4 CFLS to 3 and raised them up higher because they were drooping down way too close to the plants causing this!!:
Bottom leaf ( the worst leaf of all )
the setup now:
Hopefully they will have a speedy recovery and I will start to see some preflowers in no time.
