You're trying to control this grow too much.
Distilled water over tap.
Use nutes that have all the fert elements plants needs (there's between 11 and 16 of them).
Adviseable to use ferts that require less control. Foxfarm fruit and flower, 1/2 cup for every two gallons of potting soil. Just add water when necessary.
