I have a five stage r/o system that i would like to use for watering my babies. I have read and understand about using CalMag plus in the r/o water, but does cal mag adjust the ph? my r/o water ph tested with an oakton tester came up to 9. will i still have to use a ph up and down to adjust. I am using fax farm trio and have noticed that by adding the ff it lowers the ph to around 7.7 but of course that is still to high

FYI i am using ff ocean forest soil.
