Blister on alocasia?

Was bringing plants in for the incoming hurricane and noticed this on a newer leaf on my alocasia. Wasn’t there yesterday as I just cleaned her entirely because it’s currently being treated for spider mites so she got a full clean and wipe down yesterday. Not sure if that has anything to do with it. I last watered about 3-4 days ago and I bottom water this one. It stays outside on a covered porch getting bright indirect light most of the day and direct morning light for about an hour. Never seen anything like this before. Her leaves dripped from the tips when I first got her over a year ago but nothing like that has happened since then. Just hoping there’s nothing wrong with her, aside from the horrible spider mites of course 😭
