The last thing i changed was the hours of light. going from 20 to 12, to force bloom. and then back to 20 after they started to bloom.
im running 2x200w CFL 2700k. Im using a complete vitalink nutrients pack. and the plants are ak47 lowryder, auto and fem.

what are you growing in? what is your pH? how close are your lights? it looks like nute burn, especially if it cropped up over night.

Why did you go from 20 to 12 and then back to 20?
