Green tomatoes, brown patches

Over the past few days I've noticed that some of the green tomatoes have developed small brown patches. From googling the phenomena the only thing that I've been able to find is that they might have late blight, although all of the photos of tomatoes with late blight on the internet look a little different to the patches on my tomatoes. Has anyone got any advice about what has happened to my tomatoes and what I should be doing about it?

Disaster strikes the windowsill!

I'd just got up this morning and went to check on our little seedlings and two of the sunflowers appear to be completely wilted over! I don't know if this is because they've not had enough water or because they're getting too big for their seedling trays. I'm suspecting that it might be not enough water as they are two of the smaller sunflower shoots. Anyway, I've given them a good water this morning so hopefully they might perk up again. I did also yesterday invest in a whole load of pots and saucers so we can start repotting some of the bigger seedlings today.
