I grow in soil, Miracle Grow potting soil. My plants are into flowering since 3 weeks and some leafs are curling, so I took a measure of the run off ph with a stripe and its quite low for a soil, around 6.0. The intake water is at 7.1, If the water gets in at 7.1 and out at 6, I suppose that the soil is in the 5 to 6 range. Should I adjust my soil, if yes how to?
