your far enough along that the difference between what more you will grow with your CFL's and his 1000 watt hps would never be equal to half what you have, IMHO!

Looks like your leaves are suffering from fert burn or possibly incorrect PH or ( salt buildup). If your using RO water then perhaps you need Calmag added to the water. Should just give water , no nutes the last couple weeks anyway.

take her to harvest, man , don't think your going to be disappointed the buds look pretty good.
