yellow tomato leaves

Question

My tomato plant leaves are turning yellow. Why? I have a new garden and water the plants using the water bottle method. I have cut plastic bottles filled with water and place upside down into root area of the plants. I have used black garden paper to cut down on weeds surrounding the plants.
