What is happening to this oak sapling?

Looks like powdery mildew to me. A fungicide should clear it.
Looks like mealybugs: https://en.m.wikipedia.org/wiki/MealybugKeep them away from other plants and spray them with solutions against said bugs.
Mealy bugs are much bigger than this. This almost just looks like water residue on the leaves.
Not necessarily. At the beginning of the infestation the bugs themselves are very small and don't move much. I had an infestation two years ago.
It's little bit blurry, but what about this:
guttation
?
