If you aren't using much fertilizer, and it's organic, I wouldn't flush at all. I'd just water with water alone for the last 2 or 3 wks. The last week I'd stop watering 5 days or so before harvest, and turn out the lights 72hrs before chop. This way you minimize chances of bud mold and max thc.
Just my opinion. Use your instincts and personal insight and adjust accordingly, but you can see the method to my madness, I'm hoping.
