The bottom branches of my tomato plant have turned brown, and the higher ones are beginning to get yellow leaves. Is this from too much sun?

Tomato plants naturally lose their oldest (lowest) leaves as they become unproductive. As long as the rest of the plant looks healthy and is putting out new growth, it's nothing to be concerned about. Just trim off the yellowing leaves at the bottom of the plant. Yellowing leaves at the top of the plant can indicate sunscald or might be a symptom of too much water or a need for fertilizer. Sadly, tomato plants are subject to a number of diseases, including early blight and late blight. If the leaves begin to show spots or browning areas, they may be developing a disease. You might try applying a fungicide such as Microcop if your plants begin to develop spots on the leaves. Hope this information is helpful.
