Is someone spraying weed killer on my plants? Help!

It may seem like paranoia but some of the growth on my cherry laurels have gone black and wilted. The thing is this has only happened on the side facing out of the garden. I then went up to inspect a hornbeam I’ve recently planted and it too has withered and has crispy leaves but only on the side that’s facing out of the garden again.
Could this be wilt? Plant stress etc? Or is someone spraying something on my plants?
Would really appreciate some opinions as I’m really not sure what’s going on.

morning sun but then it moves round to the other side. It just seems to be affecting the top 40% of the plants but that is also the portion that’s above the fence...
The laurels were planted last March and I water about 3 times a week, otherwise they look very healthy. The Hornbeam was only planted this year and again one side is very healthy.
It'll pass and you'll get new growth.
Some more photos of the damage...

Hoping you are correct and just naturally occurring weather damage.
Wind can cause more problems than frost too, especially to new, soft growth.
It'll pass
I live in west central Scotland - not where that photo is...
