Late blight symptoms on leaves generally appear as irregular shaped dark spots which enlarge as the disease develops. On the upper surface a lighter green halo often surrounds the necrotic area and, on the lower surface, whitish spore–bearing mould develops around the lesions under moist conditions.
Looks more like a deficiency to me, your soil looks like it's lacking a bit of organic matter. Have you fed them properly? You either need quite a lot of compost or feed them, they are hungry crops. Although that first picture in your last post makes them look fineLast year I had blight on my tomatoes by this time as it was such a bad summer. I was a bit worried that it would hit me again as the last few weeks have been so wet. But no signs so far, I'm also in glasgow
