Q.Tomatoes and pepper plants
I planted several different varieties of tomatoes 2 weeks ago, and we have had several days of extremely wet weather and minimal sun. Now the plants look unhealthy, with yellow and wilted leaves starting from the bottom of he plant. I had placed straw around the bases of all my plants since we had some blight issues last year. Is this worsening the problem? I don’t see any bugs or spots on the leaves, or any stem issues yet. I use mushroom compost mix in the soil, but I did not fertilize anything yet. I appreciate any input! Thanks!
Yellowing leaves, as long as they're only around the bottom of the plant, are usually nothing to worry about when the plant is more mature. This early in the season though, depending on where you're located, there's a good chance it's being caused by the wet weather and lack of sunshine. Those lower leaves simply might not be getting enough sun.

The straw mulch is a great idea, just make sure it's the right type. This article may help you: https://www.gardeningknowhow.com/edible/vegetables/vgen/straw-mulch-for-vegetables.htm
