5.5 is too low of ph for soil...although your plants still seem relatively happy....6.6-6.8 for soil....5.5 ph is for water culture.....
Letting the pH creep over a range (say 5.5-6.1 or so in soilless/hydro applications) is typically even better than locking in a particular pH, and it's tough to do that anyways.
