Hello!
I have the succulent for over a month. The soil is a mix for cactus and succulents.
During the day I keep them on window for a couple of hours and because the light isn't strong enough i put them for 4-6 hours a day maybe more under growing lights (full spectrum).
I did fertilize them one single time and then i dilute the fertilizer in 1l water. When watering them i user the soak and dry method.
I have noticed some spots 3 weeks ago and I don't know why they apear. They were on the plant before the fertilization.
Does anybody knows why and where the spots came from ?
Thank you! I uploaded some photos so you can see about what I was talking!

I don't think its a major concern I've seen much worse, could be a few reasons for spots. Might just be some minor edema. May be do to your watering method. I'm not quite sure what you mean by "soak and dry method", could you explain? and do you water before or after putting under grow lights?

The "soak and dry" method is soaking the soil completly then let the soil dry out completely before watering again. The plants are in well draining soil in a pot weith a drainage hole. I usually water them in the first part of the day, i put them on the window for a couple of hours and after that i moved them under growing lights. Could be a problem with the growing lights?
Thank you for answearing me
