The crinkling may be from insects that have nibbled the embryo leaves before they sprouted. Hopefully the next batch of leaves will be OK. Or spray with a systemic insecticide such as Provado Ultimate Bug Killer.

It is powdery mildew, more apparent in this dry weather, you can spray with a fungicide or cut the diseased growth off and burn it.
