Usually fungus. You need to plant tomatoes where the sun will dry the overnight dew quickly each day. Don't water at night (water in the morning). Try to water the soil and not the leaves.
Ask your nursery for a fungicide (or if something else is causing yellow leaf in your area). They will know and guide you.
Best set to pull off the dead/yellow leaves to limit cross contamination and spread of the fungus/mold.
