I feed 1 time a week. Water the other days. When it comes to getting close to chop when the flowers are about done I'm water from there out, but I don't flush. Like kinda just stop feeding them nutes like a week or so before the chop. It's a waste to keep feeding them up to the day of the chop because all your doing is charging the soil, the plant had slowed down on uptake by then. Just my opinion, not science based.
