Looking GREAT dude. Like another poster said, just fight the urge to chop them until they are really ready. It could take another month, but it will make a huge difference in the quality of bud and yield you get.
Me and my friend are in the middle of grows and we ran out of weed. Just had to put down $210 for a half ounce of skunk x chronic. Its good shit, but I hate having to pay that much for weed. By the looks of it you shouldn't have to worry about buying anymore weed for a long, long time after you cut those beauties down. Good luck man and just try to be patient.
