Early Season Tomato Crisis

[Di Taylor]

Help. I have had a couple of bad seasons tomato wise with disease striking and losing most of my plants part way through the season. This year my strategy was to start small with some store bought seedlings: 1 Pink Brandy Wine, 1 Black Krim, 1 Sweet 100 Red Cherry and a White Cherry. Because of previous years problems I put these four plants in a part of the garden that hasn't had tomatoes for years, I used new bought compost. I did however stake them with last years wooden stakes, these were overwintered in the garage and so were very dry. Six weeks after planting and they all have issues. The red cherry has dropped its flowers without setting fruit, however this may be a diurnal temperature thing and it looks otherwise healthy, the rest however all have different issues. The Pink Brandy Wine I suspect has a wilt virus of some sort and the others I dont know. I have another dozen seedlings ready to plant out of three other variets that I have grown myself and I'm too scare to put them anywhere in the garden till I work out where I have gone wrong. Pictures for you to look at, I'm hoping someone can identify my problem and help me sort it out. PS I generally garden organically and prefer not to spray if I can avoid it.
The Black Krim has the curling leaves, the white cherry has the markings on the leaves that look like pest damage and also the bendy deformed growth... the brandywine is easy to pick cos its almost dead The last photo shows a branch that looks like it has a right angle in it, its actually and twirly bit - it really is deformed, stunted leaves and bendy branches
