My wife and I have been raising some Mother of Thousands plants for a few years, but they recently started growing brownish scales. Any idea what it could be or how to save the plants? I'm attaching a photo for reference.

Any help would be much appreciated! Thanks!

Do they scrape off? Could it be a scale insect?

Thanks for the response! They do scrape off. It's possibly a scale insect, but doesn't look exactly like the images of scale insects online. What's the best course of action if that's the issue?

Dip a Q-tip in alcohol and try to wipe some off. If it is scale you will get a sort of bloody smear on the Q-tip. If it is scale, a spray of insecticidal soap with a bit of alcohol should kill them or, I have been known to dip an old toothbrush in alcohol an gently scrub them off.

I'm not sure that is scale, although I'm also not sure whether it is physiological, a disease or damage by another pest. Has anything changed in the plant's environment lately?
