Beginner Gardening: Tomato plant nutrient sucker?, 1 by iflossu

I live in the woods and the only sunny spot at our house is our back deck. So, I have been using containers to grow my tomatoes. My mother-in-law bought me Grow Boxes this year which have been great. Anyone heard of them? Anyway, all the plants are doing wonderful except for this one...both are Yellow Pear tomatoes and were the same size when planted. It looks like the larger one is sucking all the nutrients from the smaller one. Any suggestions on what to do? Thanks!
