Powdery mildew?

So I recently bought a pearl echeveria (idk how to spell it 😭) and it has all this white powdery stuff all over it. I did a bit of Googling and I think it might be powdery mildew, but what do you guys think? And how do I treat it?

*Edit: just done some more googling and it could just be the plant’s farina? I’m not sure and would still like someone else’s input who knows this plant!

It looks like the farina. Powdery mildew will be kinda clumpy, thick, real spotty, messy and uneven. It’d likely have black/brown spots in it as well… The farina should be a thin coated layer, it looks spotty from probably being touched or water, or things like that, but that middle area is very smooth and light like the farina should be. Avoid getting stuff on it to prevent the missing patches!
@itsjordan perfect, thank you!! Yeah I was using a spritzer to get the water to the soil when watering and I missed a bit haha. Glad to hear it’s not mildew!
I agree that it looks like farina, a normal powdery coating that many succulents have (especially echeveria). It basically acts as a natural sunscreen for the plants, but will wipe off if touched.

When I was beginning my plant journey I made this exact same mistake and it’s refreshing to see somebody else do the same!! Just DONT do what I did, which was wipe all the farina off before asking Greg what it wasπŸ€¦β€β™€οΈ
@thingsNstuff oh no! Yeah that’s definitely not good. Does it eventually reproduce its farina or does it produce some and then that’s it?
@PiousWaterfern unfortunately it doesn’t grow back in most cases, but the damage becomes less noticeable as healthier leaves take over.

This is the route mine took to recover. It didn’t get enough light over the winter which is why it got so tall, but you can kind of see what I mean in these photos. She was my first echeveria so she went through a lotπŸ˜…
@thingsNstuff she looks beautiful now! Shame about the leaves that got wiped, but it’s good to know that each new leaf does have some farina yk!
@thingsNstuff She looks so beautiful and healthy now! I just found out on this thread that I did the same thing. I thought it was dust. πŸ€·πŸ»β€β™€οΈ At least now I’ll know to be more careful going forward. πŸ€¦πŸ»β€β™€οΈ Fingers crossed I haven’t done permanent damage. πŸ’š
@JazzyGardeNerd just be careful about strong direct sun. As the new leaves come in then they’ll have their own farina so eventually it’ll recover, it may just take some time :)
@PiousWaterfern Thank you! I’ll be patient. πŸ’š
@JazzyGardeNerd thank you!! Don’t worry she’ll be okay eventually, even though mine took the better part of a year to fully recover she’s doing better than ever now! It’s comforting to hear about other people making these same mistakes because I thought I was the only one until this threadπŸ˜‚
