Some of the plants ..not the heirloom ones.....have leaves at the bottom of the plant that are turning yellow. No brown, no spots ...so I'm pinching them off.
Do you think this is just b/c it has been so wet in the northeast?

If you only see a few yellow tomato leaves toward the bottom of the plant, I don’t think there is anything to worry about. It could be these leaves aren’t getting the nutrients from the soil and aren’t getting sunshine.
What kind of mulch is that under the plants? That may have something to do with the leaves turning yellow. I had that problem last year.
I suspect it is leaching due to heavy rainfall. The rest of the plant looks healthy. I would leave it alone. Are others doing the same? I reread .. you answered that question. lol
I observed your red mulch ... and there is a big marketing push that talks about using red mats under tomatoes, peppers and such. Is that your motivation and if so have you seen a difference.
I have twelve plants 6 heirlooms and 6 hybrids as a test plot with red plastic film. That same complement of plants are 60” away without dthe film.
Supposedly light wave length changes and such. Perhaps more is that the film conserves moisture around the plant. Nonetheless, I hope my crude experimentation gives some definitive results.
nutrients and fertilizer
I used to believe 100% organic
But now I like high level of humus and organic matter and a little chemical fertilizer that has trace minerals (micro nutrients) added. This fertilizer works synergistically with the humus. But if overdone the way some farmers do it gradually burns up the humus
If the yellowing moves up the plant, especially if they aren’t over-watered, and if you usually have to balance the PH with lime, it is likely a potassium deficiency. Mine did that earlier. I took a dowel rod and poked a hole in the ground near its roots and popped in 1 of my potassium pills. If you do that just be sure it is potassium and not mixed with something else, esp. magnesium. That would kill the plant. I “treated” 5 tomato plants in this manner amd they stopped yellowing and took off. If you dose up peppers only use 1/2 a pill.
I’m in Connecticut and all my tomato plants are yellow on the bottom too. I know that’s a sign of over-watering with house plants, so I’m making the same assumption here.
Finally, we’re seeing some sun!!
