I've read with my soil that I shouldn't ph it ig. I'm about to transfer to new bigger pots with fresh soil. Should I test the soil buffering like once a week?Soils can only buffer the pH for so long because the minerals that buffer the water eventually degrade and get absorbed. If you are growing in soil then, IMO, you should always try to keep your water and feeding solutions close to 6.5 pH. The only acceptation to this, that I'm aware of, is with fully organic grows.
