Flush time ?

When its a week before harvest, but i would advise you to not flush, flushing only starves the plant in the last phase of flowering wich is when the buds fatten up the most, so if you want to sacrifice some yield for a "better smoke" go ahead but the evidence that flushing actually alters the smoking experience is merely anecdotal (no hard facts) and honestly i tried flushed and non flushed and they taste and hit exactly the same, only difference was the non flushed yielded more.
