Tomato problem: bronze patches on leaves

[Bluemchen]

Any ideas? My tomatoes are in the greenhouse, and I noticed some of the leaves were a little crinkly around the edges and assumed it was the result of me being lax with my watering last week. However, there are now bronze patches on the leaves.

Does anyone know what this is and how I can deal with it? I'm an organic gardner.

Thanks

Anything on my Toms, I lop them off. Mine have a few of the same and they are coming off today. There were a few greenfly underneath; so I sprayed with ecover washing up liquid diluted yesterday. Also sprayed all toms and potatoes with Dithane yesterday as we had a blight watch near miss alert last week up here.
