That could indicate a number of problems but at this time of year cold soil comes most quickly to the front of the mind. Where in the world are you and where are these plants, inside or outside? Chlorosis, yellowing leaves, can be caused by many things starting with unavailable Nitrogen, Potassium, Magnesium, Zinc, Iron, Sulfur, Boron, Copper, Manganese, or possibly Molybdenum. Because tomatoes are tropical plants they need a soil that is warmer than most other plants might.

The sign of a good gardener is brown knees, not a green thumb.
