Tomatoes

This may sound like a daft question but here goes. The leaves on my tomato plants in the green house have all curled up. Is it the weather or have I done something wrong?

Hi Mandy, if its very warm I overhead water my tomatoes with a fine spray to increase the humidity in the greenhouse others will probably disagree but its what my mum taught me to do so..... not overly sure its the right thing to do but it seems to work
Oooh no! I'd never ever water the leaves - it just encourages fungal conditions like blight!!! Water the pots or soil when it is dry and the plants are flagging - but keep the water off the leaves
Tomato leaves do curl up - it's not usually a major problem - it can be due to fluctuating temperatures. Have a look here https://www.rhs.org.uk/advice/profile?pid=391

I never water the leaves of tomatoes I thought it could cause blossom end rot on the fruit.
I never water the leaves either - only the soil - for the reasons Dove mentions. Never had any fungal problems with my toms and they're always grown close together and indoors as we don't have the consistency of temperature up here.
I live in west central Scotland - not where that photo is...
The leaves on my tomatoes are curling up to with the heat. I'm leaving the greenhouse door open & the vents, but its getting above 40c in there some days. Will they recover when it cools?
I'd put up some shading.

Chrissy, watering the leaves doesn't cause Blossom End Rot. BER is caused by plant stress, the stress basically interfering with the plant's internal system for distributing calcium to the fruit. There can be all the calcium in the world available to the plant's roots but not enough gets to the fruit. Plant stress can be caused by all sorts of things - irregular watering patterns, strong winds, fluctuating temperatures, etc.
And, for whatever reason, some varieties are more prone to BER than others. The plum varieties - Roma, etc - are always candidates for BER even when other varieties grown around them, under exactly the same conditions, remain free of it.
