can i adjust my soil ph by using tap water or reverse osmosis distilled water, since tap water is supposed to be alkaline, like 7.0, and distilled water is more acid, like 5.5?
Due you not have ph down?? do you have a ph meter? ph the water then water is what i would do.You can flush the medium and check the run off to check ph.Assuming you have a meter.The way you want to do it will lower the ph but you wont know what it is?
