Pic would help a bit , but since there are none. What Soil are you using? What organic Mix are you using? Tap water is usually fine once you let sit for at least 8-12 hour's per 5 - gallons of water to allow chlorine to evaporate. I would start by figuring out what Ur run off of your nute solution is. Once u determine that u can adjust Ur solution to help adjust Ur soil back to PH balanced! If it to Off u can also try small amounts of dolomite add to water or sprinkled on top of soil to help neutralize Ur soils pH!
Yea one bad mani'm using a soil i buy from the hydro shop called special mix and i'm using bio-bizz organic grow,bloom and top=max.the run off is 6.5.I'm usually pretty good at solving nute defs and the likes but this is the first time i've had this one.any help is much appreaceatedand i'm in scotland where the water is usually so good and tasty for both humans and plants
