Hi, my neice planted some apple seeds from a Pink Lady apple and they developed into decent sized trees so far, I'm just wondering why the leaves have become powdery and what I should do about it?
Also yes I do know that they do not grow true to seed.

If you are able to scratch off some of the white powder, it may be white powdery mildew. Number of things could have caused the infection and a number of things can treat it.
