Any clue what the black spots are? I’m wary of anything abnormal after giving my collection mealies and flat mites. Soil was soaking wet, maybe edema? Stem is thick and healthy.

This is my first Black Prince, so I’m unfamiliar with what certain types of damage look like on these. Bullseye-shaped discoloration says “fungus” to me. All the leaves except the youngest (and the flower stalks) have something imperfect going on. It’s not visible in the photo, but the darker areas of the older leaves just don’t look quite right to me (if they rot in the next few days I will not be shocked), which may just be my lack of experience with this hybrid. I don’t believe those black spots were there when I got it a week ago, but I’m not certain. I brought it inside for a few days to monitor for mealies, which it did have of course, just a few, so there shouldn’t have been any physical damage to cause the black spots unless it reacted strangely to 70% alcohol spray (left to evaporate out of any direct light). I’m probably overreacting, but I’m already doing soil drenches and alcohol sprays on like 50 plants, I can’t let it get worse lol

The raised spots in the back look like edema which indicates that the plant was overwatered before you obtained it. On echeveria black prince, superficial wounds (e.g. chemical burns) sometimes manifest as dark spots that later turn brown/tan. Circular spots can appear when droplets of water sit on the leaves when the plant is in direct sun (this magnifies the UV and can cause burns). However, circular spots can also be edema, pest, or fungal disease-related. Look at the plant with a jeweler’s loupe to check for pests (best practice with new additions) and repot in grittier soil asap—black prince will rot in a soil mix that is over 50% organic. You want to remove all of the old soil and use lots of perlite/pumice. Then wait to water. As for the bullseye, it could be due to edema since edema is visible on the plant, and it also could be from a water droplet that burned the leaf, but I would still monitor it to make sure it isn’t fungal
If it’s just one leaf, not spreading, and looks dry/scarred > scar, edema, or burn
If you see new bullseyes forming > fungal or bacterial

It’s trying to flower. The dots are less concerning than the soil being wet

Insect bites/chow down. Monitor for spread if you suspect a fungal issue – You can always do a diluted sulfur/water mix and spray after sundown to avoid burns.
