no worries, had to talk His Lordship out of a tree more than once when that's happened! particularly leafy greens are a bugger for it, they have hundreds of fine capillaries all through the leaf that carry water. Generally check on them when the suns at the level it is now - plenty of light left, no heat, no blaze. If still wilty then, water. And don't be afraid to stick a finger in the soil! up to about the middle knuckle - the top end of your finger should have lovely damp soil sticking to it, if not, water deeply
