Looks great.

Don't let the probe dry out on your handheld meter. They are meant to stay moist all the time. Some brands put a sponge in the cap. Others sell a storage solution. It just has to stay wet. Water is probably fine.

Frequent calibration of the meter is the other necessity, especially for ph. If you do the same thing as always, and suddenly the ph is off, check the meter first.
