I planted my clones in a new soil-Roots Organics 'formula 707'. I started feeding them at a lighter dose than before. I feed at every other watering ph 6.4 and ppm of 650-700. I've only fed them 4 times. I fed them plain h2o ph of 6.5 today, I then tested the runoff of them and the ppm was unmeasureable, off the charts. My Hanna measures to 1999. Could the soil be raising it that high? Anyone use this soil before? Should I just test a pot of soil alone and then subtract that value from my true ppm?
Would sure appreciate some advice.
