my apple tree is growing healthy inside my house in Florida. it is still very young, it just
reached a foot tall. but around a week and a half ago one of its leaves started disintegrating or something? its leaf churned transulsant in parts and in those parts its veins showed brown. it hasn't spread to any of the other leaves, and hasn't seemed seemed to effect my tree, which is otherwise perfectly healthy. but still i want to know whats wrong with my tree. please help.
