Post a pic when you have another chance to take one.

Those raised areas/bumps could be oedema and/or scabbed-over mechanical injury. Few leaves are bit distorted and may have been chewed on by some pest or insect while still very small, and green fluff may have been some debris that collected on them - but I am just guessing about the green stuff. Could be algae, but that takes bit of time to grow - was it there for a while? Was it outside? Got rained on? I don't think it is humid enough now...

Sorry for the late reply.

I don't think it was there for a while bc I usually like to check my plants. But it has been outside during most of the summer. Although by the end of summer going into early fall, which was still quite warm was moved into a greenhouse. Humidity could have caused it (?) It doesn't look like anything is happening to it since I've sprayed it and I guess could be scars from being outside.

Thanks Rina :)

If it was oedema caused, it will not disappear. Leaf/leaves will eventually get old and fall off. Same if it was mechanical damage that has scabbed over.

I have this nice Echeveria agavoides that IMO got chewed on and has marks - I have to wait until many more leaves grow.
