Hydro cheat sheet: Ec/PPM goes up, PH goes down=plants require less nutes. Ec/PPM goes down, PH goes up=Plants require more nutes Ec/PPM stable, PH goes up=Equilibrium=Good thang. I read this somewhere, Is this true? I want to give my girls more nutes but the ppm goes up by a little byitself so does that mean i shouldent? Also if this is true does anyone know what about ppm goes up and PH also goes up? I am currently vegging and was wondering what light schedual is best? THe more the better? such as 24-0?
