White patches on tomato leaves?
I grow my tomatoes in a cold greenhouse, I often get white patches on
the leaves, but this year a quarter of my plants are effected.I thought
it could be something to do with the extreme temperature we have been
getting this month.
It is either very hot sunshine or freezing cold.
Any ideas would be gratefully received.
