Please help me identify these pests/plant disease! Pic included
First of all thanks for reading.
I have 2 problems:
1) On the back of my lemon tree leaves there are these white fuzzy stuff, not sure what they are....powder mildew??
2) Right under the lemon tree on the ground there are these white spots, but looks a bit different than the one on the tree...i'm not sure if they're the same.
Any help would be much appreciated! Thanks :)
