Tested run off today for the first time. Using ocean forest soil. Being that I'm in my first weeks of flowering I've add very little potassium and phosphorus and very little cal mag. Gave about 1/2 gallon of water to each plant. Both in same soil. Run off tested for 1 plant at 1328 ppm, and the other pot at 1723 ppm. Should of tested pH in runoff but forgot. Plants are in 5 gallon fabric pots.

Should I try to get it down to 1000? Or is this OK for this organic soil?

Thanks.
