What sort of meter you using mate?
Must check mine too. Havnt tested it in a couple months.It’s the essentials one. It doesn’t usually need calibrating too often, hence my negligence.

Calibrate then test your tap water, when you mix up your nutes stick the ph pen in the water first, your tap water normally doesn't vary an awful lot, so you can see if your pens drifting out. Simples. (My tap water is normally 7.2 -7.3, if it's outside of that range for a couple of times I'll check the pen).
