Hydrangea - curling up

My hydrangea was thriving in its pot and starting to form flowers, then suddenly this! The soil seems damp enough, has the cold caught it or is there something else going on?? There are a few patches that look a little like rust.
Thank you

    I'm no expert on Hydrangeas but it's possible with the recent warm weather it has put on a bit of growth and then suddenly, cold nights followed by warm days may have damaged it slightly. If as you say, the pot is well watered, it's likely frost damage on new tender leaves. The should bounce back eventually.

    I agree with @Borderline ... tender new growth has been scorched by cold winds/frosts. 
    It’ll recover. 😊

    How long has it been in the pot?
    They really don't make good pot specimens unless they're in something really big. They need the soil refreshed each year too, and it needs to be soil based compost, not just a multi purpose type.
    It's very early for it to be forming flowers too. Is it one you've bought recently?
    They're often sold at this time of year having been cossetted, and need acclimatising for going outdoors. That could well be the reason for the damage as IDd by the others. 
    It's a place where beautiful isn't enough of a word....

    I live in west central Scotland - not where that photo is...

    Thanks, that's really helpful.
    To be honest it's been moved around the garden a couple of times and then into the pot last year (not sure when) and seemed happier so it sounds like cold nights are the problem.

    Helpful to know the pot isn't a long term option tho unless we can find a spot for a giant one!
