The plant does not need watering, the dry droop is not visible in the picture. The leaves are standing up as firm and proud as a young girls titties. Unless other areas of the plant are more or less equally effected I would have to doubt it is wind damage. Wind would not only blow on such a small portion of the plant enough to damage it without causing any damage elsewhere.
Have you considered that the drying/curling might possibly be connected to the white spotting that can be seen on other leaves? Were the dried curled leaves also spotted previous to drying and curling?
