Greenhouse tomato leaves all wilted

Does anyone have an idea why a great number of my greenhouse tomatoes have wilted leaves?  Could it be the shock of cutting back leaves.

I found one of my aubergines had lots of wilted leaves yesterday, gave it a good watering and it's right as rain today. I guess when you remove leaves the plant loses a lot of moisture through the cuts, so if you've done this very recently and then had warm weather it could be the reason.
