Hi yve. I really don't know sorry. But my first thought was bugs, second thought was something nibbling on the leaves but then went back to bugs.

I'll just ask what those who are more experienced will probably ask. What is your potting mix? And can you get some close ups of some of the brown marks and some of the white things.

On your third photo there's a longer white thing on one of the left lower leaves. Would be good if you got a closer one of that

Does it get cold where you live at night? This happened to a lot of my succulents when the leaves were wet and temps dropped below 50. I'm pretty far north (upper penninsula of michigan) I've also seen this if water droplets are on leaves followed by extreme sun. Kind-of pits it with a "burn"

Could be from hard water rain that sometimes leaves white dots on succulents

Are the plants indoors or outdoors? Mine got hail damage one day. Did you check the undersides of the leaves and around the base for critters?

I had some similar looking things on one of mine. I scratched it with my finger nail and it turned out to be scale. Kind of waxy, but came off. By the time I paid attention the plant was covered so I just tossed it.

It does look very similar. Oh dear.....

I wonder how easy/hard it is to treat scale

Not an expert, but I wouldn't jump to scale. In the original photos it looks like pitted damage. Indents, pock marks. I do see some white bumps...but still a maybe.

Scale bugs actually stick out a bit and rest on the surface. If you run your finger over it there will be an actual bump to scratch off. In that picture of scale bugs above, the dots look closer to baby barnacles that the dented damage from the OP's pictures.

Im honestly not sure what the OP's plant problem is though. =/

Thanks all, I'll be wiping the leaves down this weekend and seeing what some of the white bumpy ones are. We have been getting very erratic weather and they live outside, so I'm guessing the heavy rain and hot, bright sun right after is the cause of the damage. I'll move them to a shadier spot and see if that helps. As for bugs I've had the occasional snail but they've been disposed of :). Thank you again! I was fearing mould or rot.

Thank you Rina, we just moved and they all got like this within a week. I realise now that they were slightly more sheltered at my previous place. I can now sleep easy knowing they're not hurtling towards their imminent demise. :) Seriously - thank you All for your feedback, I grew these from what was my wedding bouquet (no flowers in my bouquet) and I'm VERY invested in their survival.
