I have multiple Hoya plants that I'm very attached to! I've had them for about a year. I just noticed that they have a few white spots on the end of their tendrils. Here are the Hoya compacta:

So it looks like the white spots are underneath the waxy top coating of the leaves. If I apply pressure to them the white will, sort of, go away but most of it is still present.
I believe it might be mineral salts or calcium from using tap water in our area (guilty). I'll now be using filtered water only. Anyone have any ideas?
These spots also show up on my heart Hoya, and princess Hoya (though to a lesser extent). They're all located in different rooms so I don't think it's an outbreak.
Thank you so much everyone 💗
