Garden Pests and Diseases: Tomato problems (curled leaves, yellow spots, green inside), 1 by MTnic

The leaves of my tomato plant are curling up and most leaves are speckled yellow. Any idea if this is a disease, pest, or nutrient deficiency? I usually stick to perennials so tomatoes are new for me. The weather here has been extremely hot as of late (95+ most days) and it has also been rather humid. Also, I harvested the first ripe tomato from this plant yesterday. Although the tomato tasted ok, not great, but ok, the inside of it was green. I'm not sure which type of tomato this is (I lost the label) so perhaps it is normal, but I suspect something is wrong. Other than a couple of small to small-medium ones, the rest of the plant is filled with tiny tomatoes. Although it could have been mislabeled, I know that I didn't buy a plant that produces tiny tomatoes. Any help would be much appreciated.
