Roma Tomatoes – Black Bottoms

Question

I am planting my first garden. I have a few tomato plants (Beefsteak and Roma) and some herbs intermingled in half-whiskey cask planters. A few of my small green Roma tomatoes have black bottoms (as opposed to being all green). Should I do something about this, or is it normal?
