I don't think people generally measure the pH of their soil. They check the pH of the runoff. I grow either organic soil and do not check pH or hydro, so could be wrong on this, but it seems to me that chemical soil growers just check the runoff.
yes this is the part I am confused on. When I think about how a pH meter works I find it strange that it would be used in soil. My soil should be a balanced pH, so I believe the meter would be just for run off and to adjust my nutes. I have seen "Soil PH" meters for sale so wanted to ask if that's what people are using. Thanks for the reply, I think I will be looking at getting a normal pH meter that uses solution
