I have never seen this happen in a soil, but then again I am not concerned about the change in acidity of my soil through the length of a grow. Soil is much more resilient than ProMix in this regard and where Promix is very susceptible to the alkalinity of water throughout the grow and the nutes you are using... soil is much much less so.Nitrogen in nutrients, can drive up the acidity of my soil.
