how often do you check water ph for soil grow?

Just wondering how often it is needed to be checked? I have a gallon jug I've been watering my little ones with, and the ph seemed to have risen, but it's been like 10 days since I first adjusted it. Does it go up and down?

You should use some sort of filtered/distilled water for the plants and that you should only need to check once to make sure the pH is 7. The pH of the soil is a more important value. You should check soil pH regularly until you know that your system of growing creates the correct pH.

im going back to. if you check your water's ph everything will be fine.

I use store bought spring water and I only check it once for each gallon of water I buy. (Obviously be sure to check it after adding nutes) I've never had any PH problems.

I don't use my tap water because it likes to kill things. Not even my dog will drink it.

Well, tap water around here isn't too bad to drink as far as I know. How much does a gallon of spring water cost at the store?
