I think this is what a lot of us are seeing this year. Not blight but the fact that we are having such cool nights.

It could be the same blight that affects potatoes, Phytopthora Infestans, look around your area and see if any of your neighbours have it. It is very advanced in your greenhouse, you will have to change your soil if you want to grow tomatoes again.
