My neighbour came over today with a puzzling problem with his tomatoes. He has two branches on two different plants where the leaves have developed bright green blisters on them which eventually turn dark and burst making holes in the leaves. There is no sign of insects causing the damage and conditions are the same for all the other plants in his large tunnel house.does anyone have any ideas!
got me stumped!The only thing I can think of is perhaps water drops on the leaves getting burnt by the sun.Do they water with sprinklers!.but that doesn't go 'bright green'.Can you get themto post a photo!

Interesting as they think it might be spray residue but the blisters on the plant in the pic arent bright green and it only effects certain branches on my neighbours plants! Someone mentioned canker but I dont know what this looks like on a plant!
