Why do my tomato leaves have spots on them?

What does a diseased tomato leaf look like?
Identifiy: Appearing as tiny, round splotches on the leaves, this tomato disease (Septoria lycopersici) typically starts on the lowest leaves first. The spots have dark brown edges and lighter centers, and there are usually many spots on each leaf. Infected leaves eventually turn yellow and then brown, and fall off.
What are the signs of over watering tomato plants?
Early signs of overwatering in tomato plants include cracked fruit and blisters or bumps on the lower leaves. If the overwatering continues, the bumps or blisters on the leaves turn corky. Meanwhile, the roots begin to drown, die and rot, which reduces the amount of water the green part of the plant receives.

What does disease look like on tomato plants?
Symptoms in tomato plants are the upward curling of leaves, yellow (chlorotic) leaf margins, smaller leaves than normal, plant stunting, and flower drop. If tomato plants are infected early in their growth, there may be no fruit formed. Infected plants may appear randomly throughout the garden.

Overwatered plants may have wilted or yellowed stems and leaves, or the leaves might develop bumps and blisters or fall off entirely if plants continue to get too much water. Another way to tell overwatered plants from underwatered ones, once the case is severe enough, is to check the roots.
What do Underwatered tomato plants look like?
Underwatering: Tomato plants that are temporarily water-stressed will have wilted leaves that are still green. Tomato plants that are regularly or chronically water-stressed conserve water in roots and stems while allowing leaves to yellow, usually starting with lower and older leaves.

Leaf spot can be prevented by ensuring that you don’t cut your grass too low. Long, thick-bladed grass is more resistant to damage to the grass blades. Adding nitrogen to soil during a leaf spot infection can entirely kill an area affected by leaf spot.

If the damage becomes severe, fungicidal sprays containing copper can be used (see Table 1 for specific products). If palm fruits are used for food purposes, copper fungicides are the only approved fungicides.
What is melting out fungus?
Melting out however is a cool-weather disease where leaf spot is a warm-weather disease. Symptoms first appear as black to purple spots on the leaf blades. Spots eventually move to the leaf sheaths, and the fungus invades the crowns and roots of the grass plant.
