So I'm on my last month before my very 1st harvest and I'm wondering how long I should flush my plants...? Everything so far has been flawless and I'd hate to screw it up at the end. I was going to do the last 2 weeks with no nutes. 1st week just water and the last week with florakleen. As I've gotten close to harvest I've been doing more and more reading and there seems to be mixed ideas about how long to flush. Some people say 4 days others say at least a week...
