damn that looks just like my plant but my bud isnt that color (i dont have a camera for pics) but thats lookin pretty good just keep up whatever your doin. i would say wait to harvest until late sept. to mid oct.... if you have a magnifying glass you can look at the trichomes (the crystals on the bud) and depending on what kind of high you like you can harvest them a little early (few clear and plenty of milky trichs. maybe a few amber ones) thats if you want the more laughy happy jumpy kinda high. or you can wait it out maybe a week or less im not positive but by this time there are very very few clear, a good amount of milky whity ones, and pretty good amount of amber ones. this is for those couch lovers out there who just wanna smoke and stay attached to your couch, much more of a stoned feeling. but make sure not to wait too late as the THC will degrade if you wait too long making it less potent.
i really hope that sums up what you want to know hahha it seemed like a lot of effort (i took some hits of kief before hand)
