Why are these turning yellow? I’m using Organic Garden Soil for Vegetables.

It looks to me from the pictures that you didn't fertilize the plants sufficiently. From what I see it is a severe lack of nitrogen on the tomato plant. It appears that you live in a warm area. English peas are a cool weather plant and if the temperature goes over about 70F they will start to fade away. Peas are a nitrogen fixing plant so they don't need the amount of nitrogen that tomatoes do but they still need nutrients to produce a crop. Just because you used organic soil doesn't mean that the soil had enough fertilizer in it if it had any at all.

It appears to be old damage from either insects or, more likely, from water droplets burning the plant during the sunniest and hottest part of the day after watering or a light rain. Either way, it is nothing to worry about now as it is old damage. What does need attention are the nutritional needs of the plant.

Yes! Makes sense! We live in a very hot high 90’s and very very very dry climate and I’m sure this is what happened from watering. Thank you again!

May plants suffer from nitrogen deficiency. They can have a hard time absorbing enough, especially when other fertilizers (even ones containing nitrogen) are used, as they inhibit nitrogen absorbtion. Potatoes, tomatoes and roses are some that are notorious for this , but many others too. An application of a couple of tablespoons of common Epson Salts around the base, then watered in should fix it and the improvement is often dramatic. Repeat occasionally if necessary. On some plants, I just apply epsom salts with fertilizers up front.
