IME The best PH water levels for "indoor soil grown" strains is 6.0. Maintaining slightly acidic waterings will save most strains from a host of other problems. Hydroponically grown plants will require lower PH levels 5.5ish. That said... there are some strains that do fall outside of these ranges for optimal growth.
