    It could be something as simple as a lack of nitrogen in your soil. If this is the case, you could check the nitrogen level of your soil, or you could just add a little bit of nutritious matter to the soil and watch to see if the yellow tomato leaves don’t just green up for you. When tomato plants leaves turn yellow, it could be from a fungus or bacterial problem, like Alternaria alternata or other tomato diseases. If disease is the case, you will want to treat this accordingly. Sometimes yellow leaves on tomato plants mean that there is a pest problem that needs to be handled. You might have caterpillars or worms affecting the health of the plant and may need to handle this issue with an organic pesticide. Before you go making any adjustments, however, check the soil around your plants if your tomato plants leaves turn yellow. If the soil isn’t wet enough, you might be under watering the tomato plants; yellow tomato leaves could be a sign of lack of water. A drip hose is an excellent way to water the soil regularly to help prevent yellow leaves on your tomato plants.

    I recently learned that the roots on a tomato plant will rot if over-watered. It said to let tomato plants get thirsty (leaves will droop some), then water the the plant. I'm guilty of over-watering on occasion and the result has been the leaves turning yellow. I now water less my hydrangeas, and they are doing so much better and leaves greener. If your tomato plant has brown leaves, that could be a sign of under-watering. I don't recall ever seeing a plant with both yellow & brown leaves at same time.
