I can't see any snails or slugs. The only visible thing on the back of some of the flowers are tiny grains looking a bit like a grain of soil.
I wonder if it's got something to do with misting with that orchid food too often and if this can burn the flowers.
I am going to hold off with misting and bought a humidifier

It could relate to misting. I don't mist phals often and always avoid misting flowers.

You won't see snails until it gets dark. During the day they live down inside the pot. A clever way to get rid of the little buggers is to lay a piece of lettuce leaf on the media. Check it before you go to bed and I bet you will find some little black snails. Pick up the lettuce leaf and throw it away. Do that for a few more nights to make sure you have coaxed them all out of the media.
