Are your plants looking otherwise healthy? If so, just keep doing what your doing. PH of 5.6 isn't too bad. You could add a little lime as a top dressing to get the PH up a bit, but don't do anything drastic. Make sure that if you add lime that you don't fertilize for a week or so.

just ride it out and ph the water correctly.
