this thing is a water whore, LoL. i water with 16 oz of nute juice, skip a day, water with 24 oz of tap water with a tablespoon of molasses, it lowers ph by about a point, and then skip a day, then 24 oz of rain water (ph is a little over 6), then back to the nute juice. i use the molasses once a week, when i dont use the rain water. hope that makes sense, LoL.
