Have I been hit by tomato blight?

Leaves have dark black spots, some are going pale. Others have black around the edge.

Agree with Sunny - tomato leaves are great whingers and can display their displeasure in a thousand different ways, and it's often hard to work out what's upsetting them.

Doesn't look like blight - when in doubt I give them a weak tomato feed in case there is a slight trace element deficiency (avoid wetting the leaves, which can encourage blight if it's about and also increase the chances of leaf scorch, another common tomato leaf problem.)
