I hate to say it, but I wouldn't put a lot of faith in the PH (4-way) meter. The pen type that measures PH only for liquids have worked well for me, once calibrated. The meters with probes for soil have never given me useful info.
I'm probably a lazy grower, but I don't believe the PH varying by 0.2 or 0.3 from "optimum" is going to have negative effects. In fact, I think a slightly varying PH can be a good thing. YMMV.
Anyway, your plants look pretty good so it will be interesting to see how they do. Best of luck!
