Why does my new growth look like this?

I’ve had this alocasia for over a year at this point and this past summer recently changed its soil composition and it had been getting better light, so its growth has taken off. New leaves have been coming in back to back leaving me to prune it’s oldest leaf to create more space (it stopped killing it off on its own). My latest fully grown leaf came out a little defected, I think because it got stuck on its way out. However, the newest leaf sprout (second picture) is looking like this already and I’m not sure why. I water when the soil is a couple inches dry, letting it drain well. It’s possible the last time I watered (fairly recently) the soil might’ve been drier than I thought. But it’s been going well so I don’t know what’s happening now besides colder months. Thank you for any help or advice
