Is it frosting perhaps? We've had some plants "burn" for no apparent reason and we think it's those few really cold nights (and days - that northerly had ice in it!)
Frost/excessive sun. Often the same effects. Never water overhead either, unless it's cloudy, and make sure the watering is suitable - a good canful, then leave for a few days. Not a teacupful every day They'll be fine - the old/damaged foliage will drop off, or can be removed when it gets unsightly, and it'll produce more.
It's a place where beautiful isn't enough of a word....
I live in west central Scotland - not where that photo is...
