Yes, it could well be a micronutrient deficiency as you say.

The compressed peat pellets that the good one was started in usually
contain enough complete fertiliser to get the seedling going, so that
would suggest it is probably a micronutrient problem in the original
planting that caused the stunting.

You can see some effects of mineral deficiencies in turnips at:
