Is this normal?

Usually the crinkled leaves indicate a slightly hot mix for a seedling from my experience. Nothing to worry about. Will grow out of it over the next week or so.

The mildly cupped leaves aren't an issue at that stage if your temps are fine.

Thats early stage of calcium deficiency. Plants ussually overdrive it alone unless your pH is too low or you have unbuffered coco. To me your medium looks like peat based potting mix with a lot of coco coir added… or is it just piss poor quality coco?
