Well I don't overdo it I add three tablespoons to a 3 gallon pot and then I usually add one more when it goes into flower but I check my run off every third watering it's very seldom below 6.0 and usually around 6 3 it's pretty much right on the button with the ffofCould cut down on the dolomite to compensate for your hard water. Dolomite will raise your soil ph. If you have hard water you won't need much.
What I mean by the citric acid being my best option I'm assuming I can get quite a bit of it into solution, stronger than the lemon juice which I believe comes diluted with water, and at 3 pounds for around $9 it seems like a fairly economical option as well?
