tomato question

we are growing 2 varieties of tomato's  gardeners delight and crimson crush both are growing quite well except the gardeners delight the leaves have started to curl up and go brown on the edges and we don't know why this is happening as the crimson crush has no probs both we potted on at the same time same G/P compost

so we are unsure if we should discard the plants or not so I thought I would ask if anyone could give us some advise what mite be causing this and what should be done any advise would be much appreciated RW

Google "tomato leaf curl virus".  Does it look like that?

thank you both for your replies we thought it could be that the plants where to close to the greenhouse door and may have got cold ? because they seem to be still growing despite the leaves turning up and slightly brown

but I will google to see if it could be leaf curl Virus once again many thanks  RW

I hope you are right about the cold and it's not the virus. Best of luck to you!
