Hello all! I need help with a couple of my prink princess philos. I am not sure what is going on with the leaves. These pics are taken from two different plants. I don't see any bugs on either. Any help would be greatly appreciated. The first picture is of a leaf that is still curled, I am not sure if these edges are browned from burning or maybe something in the water. Burning doesnt seem likely considering it isn't in a direct sun location. The second leaf pictured on the other plant has brown spots. I did look for bugs and didn't see any, again, not in direct sun. So I don't know if that is malnutrition or what. Thanks!
