Problem is the "Big Mama" breed of tomato appears rather wilted, most of the
leaves are curled or "flipped" so the bottoms of the leaves are exposed. The
plant seems healthy enough otherwise. I have had no problems with insects
thus far, and the plant is continuing to grow, though is stunted compared to
the rest. I am growing them on Bamboo stacks.

Any insights?

Some tomato varieties carry a gene (wilty) which causes upward curling of the
leaflets on older leaves. "Environmental factors reported to promote symptom
development include high temperature, drought, and prolonged periods of wet
soil conditions. In addition, TMV [tobacco mosaic virus] promotes leaf roll
symptoms at all stages of plant growth in varieties with the wilty gene."
