Ph question

whats a good ph range?? I use tap water, it comes out at 7.5 to 7.8. I fill 5 gal. bucket and ph it down to 6.4 to 6.5 before adding nutes (fox farms) after adding nutes it is at 6.0 to 6.2 is this a good range and are there different ranges for different stages of growth, seddling, vegg., flowering. Also my runoff is at about 5.8 to 5.9 .. PLZ only those who know answer, no guessing!! respect to all but guessing doesnt help anyone. Thanks to all who reply.

those are good, keep doing what your doing

to better understand google ph manifesto and read the pdf that comes up

Yes like Riddleme said mate, Your doing ok atm, You dont want it any higher than 7.0. and any lower than what you have it now 6.2.
