I've got the 'aquarium' style PH tester where you compare the color of the water to a chart after adding a few drops of solution. My question is how to test the PH of water after I've added my nutes? Do I need one of those more expensive ph meters? Can anyone recommmend a good cheap one?
Ia there any other alternative to spending that much on a ph meter?
