I woudn't chop it either. Like the playbunny said, the buds will become full and dense. I would recommend that you let in grow until early october. Your plant might be done before then, depending the strain. Just watch it and I suggest that you wait until about 75% of the crystals on you bud turn an amber color. Also I read that harvesting in the early morning is the best because that's when THC levels are the highest.
