problem with tomatoe plants

Can I identify what is wrong with my tomatoe plant? The top leaves and branches look healthy but the lower leaves are curling and stems have spots. Please look at picture

No offense, but what isn't wrong with those plants? That is not what tomato plants should look like. Sorry to be so blunt, but those plants are all but dead.

You have no leaves, it looks like your stems are stretched from being light-starved (how many hours of direct sunlight does that spot get?), and fungal disease is finishing the job on the weakened plants. Also look probably over-watered. They're goners.

Here is what healthy tomato plants look like:

The pot is way too small. What soil medium was used. It almost looks like garden soil. You should use a soilless mix. The pot looks full of weeds. The fungal disease has taken all the lower leaves and will soon consume the rest of the plant. I agree...goner.

The pot is full of weeds and the saucer is full of water, not good growing conditions for any plant.

The pot is too small and it looks like the tomat has been struggling for some time

If you plant in pots then lose the saucer.

Select a pot that is big enough. If you have a dwarf tomato then a small pot is enough. If you have a determinate you can get away with a five gallon pot if you feed it well. For indeterminates you should have at least a 15 gallon pot or bigger. I like 18 gallon pots. Indeterminates will get 8 ft tall or more so put a trellis in when you plant.

In a pot, choose a good potting soil, not dirt. Add 1/2 to 2 cups of vegetable fertilizer and either mix it in or divide it and give 1/2 cup in the starter mix and give the rest in divided increments monthly over the life of the plant ( 1 tablespoon on the 4th, sixth week and monthly thereafter. I have a tomato fertilizer that is 9-12-12 and it works fine.

Plant your starter tomato deep. Choose a variety suitable for your climate.

Mulch the pot to keep weeds down. Water thoroughly daily, but try to avoid wetting the leaves late in the day. It is best to water in the early morning.

Remove the lower leaves from the plant, they will get disease first.

Treat problems early. Check for pest and pick them off or select a method that takes care of the problem with the least toxicity.
In hot humid weather, you will need to do preventive fungicides.

Birds and pests will go after good fruit, so you will have to bag or net them. They don't go after fruit that does not taste good.

Tomatoes should have 6 hours of good sun, but pots get hot and cook roots on cement. So put the pot on a dirt surface or put the pot inside a larger pot to insulate it from the heat.

I agree with what everyone said and the plant that's in frame all blurry doesn't look to good either.

This was a post from last summer. The OP never came back, so I think we can quit beating him up about his poor tomato plants.

I missed it before, but the stem that is close up on the right side of the picture has dark blotches on the stem that may be symptomatic of blight. When plants are struggling as this one was, with not enough light and not enough nutrients, they are very vulnerable to whatever pests/ diseases come along.
