Flushing actually can take out contaminates that some fertilizers and water brings in (salt, etc...) I wouldnt constantly flush a marijuana plant unless it is drooping and doesnt seem to be healthy for a few days. But you should flush your plant 2 weeks before harvest to get the bad taste of fertilizer out of the bud. Everyone has their own techniques. Flushing will take the nutrients u fed into the dirt away. You will need to feed after you flush every time. Its a waste IMO.Hi I was watching a video on youtube over greenhouse seed's hawaiian snow grow. I know this is a total noob question but.......one of the guys in the video keeps talking about "flushing" to keep the plant healthy. What exactly does he mean by that and how would it be done?![]()
those guys feed real strong and flush like every two weeks!!!but they are basically getting the salt buildup out of their medium so they can continue to pump nutes!!!
