If you still feel it's a pest issue, you can treat the plants with neem oil. It is effective and safe to use. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
I've had the same problem with some of my tomato plants! :(
I think they're being eaten by critters / insects that have found their way to our precious tomato plants!! lol!! I've picked 2 green worms off of my plants over the last few days. Other websites I've gone to suggested either using Sevin dust or a comparable insecticide for vegetable plants, or checking your plants carefully daily & remove any worms that may be found. Look carefully though!! They are EXACTLY THE SAME COLOR AS THE TOMATO STEMS! They also munch on the leaves, & I've found them on the underneath side of the stem. You can also know if you have them by looking for little black poop drops on the leaves.
This is my first year growing tomatoes, so I'm no expert! Just sharing what I've learned so far! :)
