I was just wondering. If I was doing bubbleponics (not top fed). And I wanted to get all the nutrients out of the plant before harvest. Would just giving it 2 weeks of nothing but plain water before harvest. Would that be enough to get all the nutrients out of the plant?
That's what I do. Just feed them less at the end. I've flushed and not flushed and there was no noticeable difference, so I don't flush at the end. I do periodically flush for 24 hours during the grow.
