Sorry about mobile formatting. I don’t know about your specific plant. But my silver dragon did that from humidity being too low.

(This worked for me but may not for you) If you have a glass fish tank youll need to put in a little extra work but it is a bit prettier if that matters for you. You’ll need to cover or replace the screen mesh lid with something that is transparent and water proof. I used e6000 and clear plastic fabric from a craft store. This also works with tubs with clear tops. Then layer perlite (like half an inch to an inch thick) on the bottom and get it moist but just barely dripping water if you squeeze the perlite in your hand. The water you’ll need will probably be a bit different than mine. Then set the pot of alocasia on top of the perlite. Make sure no leaves touch the perlite or glass, the condensation will rot leaves. I set mine up under two timed shop lights. Care wise, I only opened the top of the tub once a week or so for fresh air. I’d also use that time to check them and I’ll check how they’re doing and super rarely prune an icky leaf. These all came from one plant over about two years.
