For soil add espoma soil acidifier to go down and garden lime to go up. For hydro use ph up/down solns. I prefer an Apera meter. Test before going in and what the runoff is to know what to do.

For liquid feed Bunnings Manutec have a pH up and down as part of their hydro range (just saw it in an other post) and a drop based pH test.
Just be careful if you are close to the EC limit as the bits of pH up and down that are not acid or alkali tend to be salts and add to EC - especially if it bounces up and down and you readjust.
