What are you concerned about? It looks ok to me...some critter may have chewed on it or something else may have caused little physical damage. But other than that, I don't think there is any problem.

I wasn’t sure if the white in the top center of the flap jack indicated anything as I thought it should hold the green color?

The white is a good thing, it is called farina, which is an Epicuticular wax. It protects the plant from sun rays and helps repel water.

Some succulents are covered in the stuff.

Echeveria colorata

Dudleyas are probably some of the whitest succulents around.

It rubs off easily so try not to touch it.

Thank you very much!!
