I have this plant for a month now and it started wilting for no reason, does anyone think they can help?
I don't think anything is wrong. The damage appears to be on one leaf only, and not in the axil, and not on the newest growth. It could be some accidental damage or it could have been touched with some chemical it couldn't tolerate. It doesn't look fungal, and the rest of the leaves look fine. You can either ignore it, or snip just the dead part out.
Do. You think incense could cause the damage? I light the incense in a different part of my room though
