why are my tomato plant leaves turning yellow?

Question

The leaves on some of my tomato and pepper plants are turning yellow. Is this from too much water, too little water, or something else?

Answer 1

Your drowning your plants, you should only water your plants once per day, and only about 2 - 3 ounces of water per plant.  Watering should be done in the morning so that  the plant can use it during the day in the leaves.  Too much water and the leaves lose their ability to produce what the plant needs, equally too little water and the plant will shrivil up and die. -Birdy
