Does anyone know what's causing this? I got it a few months ago from someone and the leaves already had these spots. Every new leaf unfurls with the spots. Last pic is of the newest leaf. I check constantly for pest and theres been no signs of any so I don't think it's that but I've been treating it as precaution. It originally was in leca when I got it and wasn't sure if it wasn't liking the leca so i transfered it to soil and it's still happening. I'm lost
