Im not exactly sure as I have not made it to that point yet, but from what i've read and heard you basically give the plant pure water with NO neuts for the last 2 weeks of its life. I believe they sell an actual flusher at hydro shops that you mix with your reg water. Do a little research, im sure you can find it at most hydro stores.

I think to start flowering depends on your grow room size and how big you really want them to get. Most start in the 4-8 week range by switching the light cycle to a 12on 12off schedule.
