The blossom end rot is from calcium deficiency. For now, you can try feeding them some milk. In future plantings, you may add a handful of powdered milk to each hole or you amend your soil with another material full of calcium (oyster shell, egg shells, bonemeal and some kinds of lime).



Some people say overwatering is what causes blossom end rot because some kinds of calcium can be washed out of the immediate area by lots of water.



The tobacco mosaic virus is pretty rare but it does happen and it can affect plants other than tomatoes. If you find it in your garden, then next year use varieties which are resistant (lots of tomatoes are) because the virus can linger for years.



If it is a fungal based infection, then you can try baking soda:



1/2 teaspoon baking soda, or 1 teaspoon for stubborn control

(2.464 cc/ml or twice that much for stubborn control)



1 quart of water (1 liter)



Here is a page with pictures of tomato plants. Each plant suffers from a different nutrient deficiency so maybe it can help you with your diagnosis:

Kelp/seaweed is probably the most complete source of micronutrients. Tree leaves and fruit skins are also a good source.
Reply:Without Pictures it is hard to tell, but I suspect that its either the weather or a virus or both. I havent had blossom end rot for years and unfortunately am not at homoe so cant look up the book for you but from memory that was caused by irregular watering although it doesnt seem to be your situation. The curling leaves could be just hot weather and wind burn but I would spray them with a good fungicide as a precaution. Another thing similar to what you describe was some virus that they can get from cigarette tobacco. I dont smoke and a whole batch of plants went like that once and and insider at the nursery told me that they lost a lot because they get a virus from tobbaco and people who smoke are not allowed to touch the plants or something like that and a new person had been doing so and caused a huge problem for them. Sorry cant be of much help but if all else fails ask the nursury you bought it from- regards from Tassie.
