Yellowing Leaves on Tomato Plants
It could be any number of things.
First, as the plants mature, it's not uncommon for the bottom leaves to yellow due to lack of nutrients from the soil, that the weather is really hot, or even lack of light (the top leaves are shading out the bottom leaves). It's ok to pinch them off. And, don't worry about all the plants dying quite yet.
Next, do a soil test. It could be a lack of nitrogen in the soil. You can take some soil from around the base of the tomato plant to your local extension service and they can help with the test. There are also soil test kits available for purchase, but the reviews I've seen on them don't inspire a lot of confidence.
Your best bet is to test the soil and go from there.
P.S. Do you rotate where you plant tomatoes each year? If tomatoes are planted in the same place each year, the soil becomes very nutrient poor and diseases are more likely to be a problem. If you don't rotate, you should start next year. If you have the space a 3 year rotation cycle is optimal.
