Since these are container plants the odds heavily favor nutritional deficiency but there is no way to know that with much more info from you. Like what product, how much and how often are you feeding them? Indeterminate varieties in containers sized such as in your pics would require weekly feedings of some form of supplement.

The Brandywine leaf in the last pic looks like Early Blight as it has the bulls-eye patterns. The leaf roll on the Stupice is called Physiological Tomato Leaf Roll (you can Google that term) and is caused by inconsistent soil moisture levels - wet/dry/wet/dry. Once the leaves roll like that it doesn't go away but you can prevent it from getting worse by changing your watering regimen to try to stabilize the soil moisture.

The first 2 pics look like Bacterial Speck/Spot rather than Early Blight and both bacterial and fungus diseases ( like EB) have the same treatment - remove all affect foliage from the plant ASAP and dispose of it. Then begin a regularly scheduled fungicide spraying program with a fungicide (copper based for bacterial issues). It won't cure it, just slow it down.

The Sun Gold looks like it is getting root bound in the pot and the yellowing leaves are most likely from the over-watering that results from growing a variety with a huge root ball in a small container. Sun Gold is notorious for being a huge plant with a huge ball and to do well it need a HUGE container of 20 gallons minimum.

Hope this helps some. There are numerous other discussions running here now, especially on the Growing Tomatoes forum, from folks with the same problems as you so there is a lot to learn from reading through those discussions too.

In general, your plant is sick...for some reasons.

Like what dave said, take off those affected leaves, dispose them properly, apply the chemical treatment.

Here are some tips though to help:

* Eradicate those white flying thingys if there are - the aphids. They are vectors or carriers of fungus as well as virus. The fluid of those are sweet for molds to form...fungus.

* If you have some marigold, try incorporating it in your garden...they attract lady bugs as well as other beneficial insects. The type of insects that will feed on those destructive insects - aphids is just one.

* Leaf curling as shown in the picture - apply fertilizer that is high on phosphorus and potassium and less on Nitrogen.

* As your tomatoes are fruiting, try adding some calcium for its diet. This to help avoid fruit rotting.

* Do take precautions when applying those inorganic fertilizers, the NPK types. Plants love it so much that they produce more aromatic amino acids too. This type of acid is responsible in attracting insects.

* Lastly, make your plant healthy so it won't be badly damaged by fungus, bacteria as well as virus. Moreover, it wont be weak during extreme conditions...diligence too is needed - cleaning its surrounding environment (dead leaves, no smoking, etc...)
