Cherry tree problems

I have a cherry tree I planted about 3-4 years ago, it’s 5 different type cherry grafted onto a common root stock. 3 sweet and 2 savory. I’ve had great blossoms every year on it and last year there looked to be loads of cherry buds starting but looks lovely me the local bull finches had a party with the buds. This year however after a great cherry blossom i then had some strang happenings. There seems to be the buds dead, and the leaves seem to have picked up a disease. Any ideas ?

           

Can do you think it could be blossom wilt?

My apples are in the same condition.

Mine is exactly the same . I put soapy water on it in case it was a bug. Not so sure though?
