I'm new to this online community but I've been growing succulents for a few years now. I have a concern about a few of the ones I have. 4 out of the 10 have started showing small brown scaly patches on the leaves. They showed up within the last day (I look at all of them every morning and didn't see them yesterday), can you all help me identify the problem?
Since coming on here, I've learned that there are a couple other signs in almost all of my plants of them not getting enough water and sun (aerial roots and stretching, respectively), so I'm not sure if this is another symptom? The photos aren't great but hopefully you'll get the idea..
Thank you in advance!
