African Violet Diseases is it Really?

Question I have 60 African violet seedlings in 2-inch pots and a number have odd crisscross veinings in the leaves. One plant has a pinkish hue on top. These odd markings do not seem to hurt the growth but what causes them? Is it a disease? AD, Neb.

Answer Since your seedlings are making healthy growth I am inclined to think the odd color markings are just natural variations that may result in giving you some very interesting plants.
