Experts for what. You guys just make to big a deal over it or don't listen. PH your water if you want, it won't hurt. I don't and have no fing problems along with everyone else who don't PH ! But I have set my soil up do to so and this grow has been organic, IF you are feeding SYNTHETICS I suggest you PH your feed solution . All Ph does is keep the feed solution in a range where the plant up takes it best. In between waterings with out PH will be fine for you synthetic guys.
