Alocasia zebrina. No pests found on plant. Has definitely NOT been overwatered or underwatered. In my bathroom that has a large window that is east facing. It may have received some direct sun in the mornings until 11am-ish. About 8-10 feet from window, but rays do go to the area that it was. I’m thinking it’s a burn from the sunlight, since I’m pretty sure I’ve eliminated all other factors. I’ve never had this happen before and don’t trust myself yet on the diagnosis. Hoping I can get confirmation, or if you don’t think that’s the cause, of what you think are possibilities. Thank you for any help in identifying what caused this.
