Im new to organic growing, I use Gh-ferts and others, happy frog soil, my water is a perfect 7.0,,, when the ferts are added, I have 6.0 most of the time, sometimes I get a 5.0 reading which worries me a little so I was looking at organic ph up & ph down which opened up a million schools of thought,,,however, when I read the run-off it's always a perfect 6.0. should I be concerned at all with these readings? I feel like thats perfect but im severely anal retentive and perfection is all Im able to handle. Should i be content with these readings?
