nice work tomuch,plants look good. Id give em another week then post some pics. To flush or not to flush?? I don't, never have. I don't know how anyone could say if you don't flush your gonna taste chemicals when your grow method wasn't stated, could be all organic. I think people who need to flush are probably the people who spend hundreds of dollars for 17 bottles of additives, a bag of sasquatch dung, and whale semen just to flush it down the drain anyway, but to each their own.
