There are several possible causes for yellowing ranging from under to overwatering, under to overfertilizing and possibly pest or disease problems. If you are using a watering system, make sure it is watering evenly. Also inspect the plants carefully for insect feeding or other damage. If only the oldest leaves are yellowing, try feeding your plants a little nitrogen. Wish I had more suggestions!
