looks sweet rule of thumb when u think its time to harvest wait a couple more weeks but checkign trichomes is the only real relevent way to know..ww mostly indica for a up high u want the trichomes mostly clear to cloudy at harvest time for a narcotic sleepy high wait a few more days for mostly cloudy to amber trichomes...as zandor has pointed out previously once u have mostly amber trichomes thc production has begun depleating itself and the plant isno longer in its prime but ona downward tilt...great grow keep it up!
