Im about to start up and i was testing my tap water ph before i presoak my rockwool and it came out to 7.6 and change. I was thinking this is a little high and im wondering if there is something wrong with my ph pen. Is tap water normally this high? also what can i do to calibrate my pen? Thanks in advance.

have you ever calibrated the pen?

tap water can have all sorts of ph levels.... just adjust the ph before soaking your rockwool.
