Hi Adreskaja,
Your stem is bend because of the wind. Try to turn your pot 180 degrees once in a while.
Those white spots can be milddew, since the picture is a little bit blurry, i can't say that for sure.
It could be some dust as well....
If it is milddew i have a cheap solution for you.
Get yourself a plant stray with 900ml water and mix it with 100ml milk.
Spray your leafs with it when there is no sun on your leafs otherwise she will get a sunburn.
You should make sharp pictures for us to see what is on the leafs.
Good luck growing :)
