Turnips, and other members of the cabbage family, are often attacked by flea beetles, small beetles that eat small holes in the leaves and can severely weaken seedlings.

A dust of derris or similar will deal with a severe infestation, but if there are just a few spots, the damage is not significant and no action is necessary.
