Tomatoes - Is this blight *photos attached*

[WelshBoa]

Hi

I have been away for a week so had to remove the polythene cover off my greenhouse frame and hope we had rain!

I have come back and noticed the following. Admittedly the lower leaves on most of the plants had discoloured in this way, but all the fruit was fine and green when I left.

Should I remove the tomatoes that have this discolouration? It may be something harmless which wont spread to other fruit on the plant but want clarification. Just to note I only ever water at base of plant and feed twice a week on average. Plants have been under polythene covered frame from day 1 and this is first season. The first image shows some of the healthy fruit with a little scarring I think.







Hope the image code works!
