My plant has been very healthy for the past few months but recently these black and brown spots have been popping up and the leaves have been dying I tried to cut the whole stem to see if it was just the infected leaves but it seems it has spread to the rest of the plant. I checked the soil and leaves for any spidermites or any other bugs and didn't see anything.

Any thoughts? Anyway to recover the plant from this?

Thanks!

Your photo is too blurry to tell what it is. Can you rub the spots off with your finger?

Sort of! If I use my nail slightly they come off. Should I scrub them off?
