If ppm is to high add water to lower it. If it's to lower add feed to raise it. As for the ph question, I'm not able to help. Lucky for me my ph stays stable between res changes.

it really depends on whats causing high ppm--sometimes IT is the water! my out of the tap PPM here is 570+ RO water is best for adjusting high PPM, but there are times when you have to dump what you have and start over. you would have to be the judge of that.
pH can be adjusted with simple pH Up or pH Down. This can be gotten from pet stores or pool supply and goes a long ways. most RO water is well-balanced in pH.
