Apple tree relief? ok so i planted an apple seed and im trying to grow...

ok so i planted an apple seed and im trying to grow a tree. my tree has seem healthy untill now. the stalk is turning sickly and there is some kind of white flakes on adjectives the leaves. originally it was on just one of the leaves but very soon it has spread to all of them! i poked holes surrounded by the cup and a bunch of water spilled out. is the plant just getting too much hose down or am i looking at a big problem here?
thanks for your help.
Name that plant?
Answers:    Sounds similar to you might have a dampening off problem. This occur when there is too much moisture and not enough nouns flow. Unfortunately it sounds like it may be too late. Try to embezzle off all the infected leaves and replant it contained by new, fresh soil. Keep it moist but not soaking wet. If every ending leaf has it and is curling up after your chances are very slim but a retrieval could happen.
