I have well water, thats it, its alkaline(green) and needs to be ph a lot, to get it down to 5.5 /6.0 ... I am not getting the water from the faucet cuz it uses a salt/filter system for the drinking water, so I use the old outdoor hand crank and get it right out of the ground (more minerals in hard water so is that better for the plants right?) anyways, I swear the waters ph is climbing back up, I checked a leftover bucket of solution after a few days and it was higher! (or I was ...lol) is this normal?
