I am new to this, and I have a few qustions on PH. It sounds to me that their are different ways to correct PH problems, 1 is to get the water PH to be such that the soil ph will correct, (soil has ph of 5.0 so using water ph 7-7.4 will get you soil to ph of say 6.5/

The other is to use the PH water at 7.4 and just adjust the contents in the soil to make the PH correct using lime or other items to bring the soil up or down.

and I was told that you can add epson salt to correct the ph too.

I am doing the 1st methold where I am setting the water PH to 7.4 to yeald a 6.5 ph but my soil is not taking it down enough so I will be using a water PH of 6.5 lets see what happens.
