That's kinda what I figured I've been gardening for several years now and it has been a learning experience the whole way. I personally do not ph my soil because of buffering affect and because if it ain't broke don't fix it but there's some people who feel the need to ph in soil grows ..... In my own personal research I have also found that some of the products used to adjust ph can actually kill good things that we want in our soil microbes etc ..... Like adding store bought ph adjusters and mixing it with molasses will actually defeat the purpose because some ph adjusters will kill the microbes in the soil and molasses ..... So thanks for your input because I've found this to be a pretty touchy subject the whole ph soil thing
