dont know what they call it but i am getting the same problem on 3 of my 14 plants, i have stripped all the infected leaves and it dosen't seem to have affected the fruits or the other plants..i have grown in the greenhouse for 4 years and never had this problem but i don't remember the summers being so unpredicable as this one and especially the drop in night time temps...hope this helps

I wonder if the pictures on these pages will help you to identify the problem?

I had this too a while back - and stripped off the affected leaves and gave the plants a good feed. They're fine and still have some copper patches on them. Never got to the bottom of what caused it.
