Anyone know why my tomato plants (outdoor ) have leaves that are curling. it's not the dreaded blight is it ?

    It won't be blight - that's horrid blotches on the stems and leaves.  

    Can you post us a picture of them so we can see how they're curling ?

    Leaf curling is usually down to draughts (assuming soil/water is ok)- don't think it'll do much damage, but if there's some sort of windbreak you can provide will help.

    Plants by the greenhouse door often curl when the doors are open
    Good luck!

    Yeah mine have started doing it, i'm assuming its weather related, thunderstorms followed by blazing sun and back again.

    Tomato leaves usually curl because of temperature fluctuations.

     However, if tomato leaves roll inwards from the sides to the centre, this is usually due to over-watering.

    sometimes they curl because they're happy!

    Sounds like you're definitely overwatering, Irene, which - as Dove says - will cause leaf curl. I responded to your question on Simon's thread.

    For toms in the ground, the rule of thumb is to water infrequently but deeply. This sends the roots deeper into the soil. Frequent shallow watering only keeps the roots hanging around the surface. As an example, mine are in the ground, the temps are now into the mid-high 20s, and I'm not watering more than once a week. But when I do water it's deeply. 

    For toms in pots, the mix should not be permanently damp. Few plants like constantly damp feet and toms aren't one of them. You can afford to let the mix dry out between waterings. And when you do water, water deeply.

    As an overall rule of thumb, toms thrive on "tough love". Or, in other words, controlled neglect. A tom produces fruit in order to reproduce itself before it expires and your basic aim is to create an environment in which the plant feels a tad threatened, encouraging it to reproduce. An overwatered, overfertilised plant doesn't feel threatened, just bloated. In short, less of everything is better.
