Drying and dying leaves?

[awsumth]

Your soil has too much disease. I've seen that problem with every tomato planted in the ground in Florida. First the roots knot up which causes the plant to become weak. Then fungus in the soil splashes up onto the leaves (once after a hard rain my plant was nearly covered in sand). One problem often is enough to cause another. At this point the plant might not be worth saving. Try your best to keep your tomatoes sanitary.
