Answer 1

Have you been spraying weedkiller nearby, if so this is what is known as  'drifting'.  The fine spray, often invisibe, is spread by the breeze onto the foliage. If not too much has got on your plants they will recover. Thats why it's got ' do not spray on a windy day' on the bottle or packet.
