Yellowing Tomato Leaves with Brown Freckles: Virus or Blight?

Cool, wet spring then dry. Lower leaves yellow with grey-brown freckles. Could be Tobacco Mosaic Virus (TMV) if smokers handled plants. Symptoms: mottled leaves, fern-like new growth, brown stem streaks, mottled fruit. If TMV: remove/destroy plants (burn/bury), sterilize tools/hands. Also consider early blight (concentric rings) or septoria (tiny dark spots). Improve airflow, mulch, avoid overhead watering. Rotate crops yearly.
