Tiny spots on Echeveria epicuticular wax layer

Asked September 20, 2018, 8:43 AM EDT

Hi! I need you help with my echeveria. I noticed tiny spots on the leaves. They are not brown, white or black. Actually they look like some kind of breakage of it's natural wax layer.
I didnt't shower them 'cause I know echeverias can burn on sunlight if it's showered.
I made some photos for you. Please, help!

Hi! Thank you for your question. The photos look like edema.

Sometimes when soils are wet and uptake of moisture is faster than transpiration (water loss through the leaves), plants may show edema symptoms. Edema is a non-infectious disease, typically caused by the excess moisture available to the plant. This fact sheet provide for further explanation:
