Answer: Although we often think we have treated plants all the same, there is occasionally something that is different -- indoors, we may water that one less because it is hard to reach, or the lightbulb may be dimming in that spot for instance. Outdoors, there may be a rock under ground impeding the roots or there may be a different level of soil amendments in that spot; the drainage may be different or some other factor may be slightly different. If nothing like that seems to be causing the problem, there is always the possibility that the individual plant is a poor one since there is always some variaton from seedling to seedling. Although I am not familiar with that particular tomato, I have also occasionally seen plants that seemed skimpy suddenly kick into gear and grow once the weather and soil are truly warm. Perhaps that will happen with this one.
