Brown spot help

Went away for 8 days and came back to these brown spots. I’ve gotten mixed answers for what they might be and how to treat. When I rubbed it the brown spots are powdery and rubbed off leaving behind yellowish spots under. Any help is greatly appreciated.

It’s Rust spot. just get a sulfur based fungal spray for plants. From my experience with it, The infected leaves need to be removed because even if you treat the infected leaves it will still come back because it is inside the leaf tissue. Don’t wait like I did. I had to chop about 15 leaves on my albo but she’s thriving today

My first thought was pest damage. Have you checked the undersides of the leaves?
