Cannabis's Proper Hydroponic pH Range is from 5.5 to 6.1. At a pH of 5.5 to 5.7 your missing the nutrient availability of P and Mg. At a pH of 5.9 to 6.0 your missing the nutrient availability of Ca. And at a pH of 6.1 your missing the nutrient availability of K, Ca, Fe and B.
At a pH of 5.8 - N, P, K, Ca, Mg, Fe and B are all available for consumption by the plant.
All and all, if your using Rockwool for germination or cuttings, pre-soak your cubes in a 5.8 pH water.
