your soil is fine. 7.0 is the standard most quality soil uses and i'd be very happy with that 7.0 if i were you. it'll come down a bit as you add the ferts and rain water is also usually on the acidic side so don't worry about it. if you're using tap water it's much more important to test it and adjust as needed but there again don't worry about a half a point here or there. more harm can be done trying to fix something that isn't broke in the 1st place than would happen if just left alone most the time.
