    The weather could very well be the problem. When temps are above 85 F, tomatoes slow ripening. When temps are 95 F or higher, tomatoes can stop ripening all together. Many parts of the country are experiencing high heat, and if you are as well, this could cause the tomatoes to either ripen unevenly or stop ripening all together. It should correct itself when the temps come down.

    It sounds like stink bugs to me. They suck the juice out of tomatoes leaving green hard spots on the inside. If your other varieties are doing the same thing, look for brown or green stinkbugs. Sunlight might be a problem if they
    are not getting enough sun.

    If the leaves look like they have a white powder on them, that is powdery mildew, a fungal disease. Please see these articles about it:

    Another possibility is tiny white pests on your plants. Some insect pests can appear white, such as whiteflies, thrips, and scale insects. If you have these, you'll be able to see them if you look closely.

    Spindly plants are usually not getting the optimal amount of light. If your plants are producing enough fruit, though, it's probably fine to keep the light level where it is, and the spindliness is just an aesthetic problem. If you want them less spindly, you may need to place them near a window too, or you may need to add more grow lights or a mylar reflector. Adding too much nitrogen fertilizer can also cause plants to grow taller too quickly and become spindly.
