I have recently read about adding nutrients to re-circulated mixes....but I am not sure what this means. We grow hydro and have 20 gallon res. tanks. We clean them every 3-6 weeks but I add nutrients every other week and mag every week. When I add to nutrients to tubs that already have nutrients, could this be confusing the plant or harming it? Should I clean tubs every time I add nutrient? I never check the ph before i add nutrients but it never fails that we add ph down every day or every other day, is there a reason our ph is fluctuating so much and is there a way to stabilize it? Another question about salt ppm....we have a digital reader which I was using religiously but was having trouble controlling the salt. Is there an easy way to lower salt in our tubs? Nutrients really shoot the ppm up, sometimes way above 2000 ppm in the veg room. Does anyone have suggestions on lowering salt? And stabilizing ph?
Thanks So Much :smokin:
