When should i start flushing my dwc hydro bucket?

Hello. I flush and will always flush. I think it helps despite the report. There is a fertilizer company that did a flushing study ( they could make millions if they could get you to stop flushing) and this study says there is no difference between flushing and not flushing. I quote Ed Rosenthal: Plants react quickly to (the flush) this sudden change in the environment, by focusing on maturation of flowers rather that continued production of flowers. Please read: edrosenthal.com Flushing Cannabis Guide. Make up your own mind about this controversial subject. I can tell the difference between flushed and unflushed cannabis, maybe you can too. Good Luck. Chuck.
