Is this tomato blight?

I don't think so - it looks very different to what I've got on mine!

The worst bits had brown spots in the middle of the yellow areas.

On my outdoor tomatoes, the bottom leaves have gone completely brown and I've pulled them off - the leaves further up are also going brown, now. I'm just waiting for signs of rot on the main stem, then I'll pick all the tomatoes and destroy the plants.

Dont thinksi its blight, may be a deficiency of food, or it maybe because its been wet and cool. TOms dont like temperature below 10-12C

check out my photos for blight!
I got it bad this year! ! !

it looks like a mineral deficiency. give it a good feed. it is also normal for the lower leaves to die off as the season progresses. pull them off and feed it.

everything is well fed now, fingers crossed!
