PPM slowly rising

Is it normal for the PPM to slowly rise over time?

My lettuce has been in my floating raft system for about two weeks now and the pH has stayed nice and stable around 6.8 but the i have noticed the PPM is slowly rising.

pH over the last two days has dropped just a tenth or so i will check today and see if my pH is slowly dropping also.
