Causes of Yellowing Leaves. Common causes of yellow leaves on tomatoes include cool soil, age-related death of the lower leaves and a myriad of nutritional deficiencies including nitrogen, boron, potassium, iron and magnesium. Leaves may also yellow when affected by fusarium wilt, bacterial wilt or verticillium wilt.
Early blight shows up as a leaf blight on the lower part of plants. The disease moves upward, and by early to mid-summer, early blight has caused a firing-up of foliage over most of the tomato plants in the garden. As the disease progresses, leaves turn yellow, wither, and drop from plants.
