Yeap, my hydro shop said nute everyday and I have no problems with it. I tried the 1 day on and 1 day off but saw slower growth. As for pH, with my faucet water I need to add 4 drops of General Hydroponics PH Down per 1.75 liters (my water container).

I usually use all my nutes in a day and have little to none left over, which I toss and make fresh again every morning. I add water, ph down, A, and B in that order every morning. Sometimes I add a drop of Superthrive but can't really say it does anything, can't hurt.

:hippy:
