I'm no hyrdo guy but its probably just like when you grow in potting soil or whatever... 2 weeks before harvesting. But seriously dont take it from me id actually get a hydro mans/womans input!

Anytime between one and two weeks before harvest. You can just use plain RO water, or there are some flushing additives sold at the hydro stores. I've tried both ways and can't tell the difference.

Is it absolutely necessary to flush one or two weeks before harvest? What is RO water?
What if you had a few plants 4 weeks into flowering and you had a few plants that you added to the flowering room later that were only 1 week into flowering? Have you every had to deal with that situation?
