Q.Yellow leaves on tomato plants
We just planted about 25 tomato plants and all of them all of a sudden have yellowing of the leaves. We were very careful to put the best soil in so we do not think it’s that. Also, we water the plants in the morning and in the night and it gets plenty of sun. Any other reasons why the leaves are turning yellow? It’s definitely from now enough caring because I take very good care of my garden. HELP!

Most likely it's from shock, though tomatoes turn yellow for many different reasons. You can treat them like they have transplant shock to help them recover better. This article tell how to treat plants with transplant shock:
