Monstera seems to have a disease, help identify?
I just purchased a new monstera about a month ago, and just recently noticed that the bottom, smaller leaves began turning yellow. Upon further inspection, I noticed many small black spots on the leaf as well (both top and underside). As I look at the additional lower leaves, there are some green ones that have the same black spots but are not yellow. I worry that there’s is a disease spreading and need advice how to fix before it’s too late!
