tomato plants with yellowing leaves

[dancing homer]

I have noticed that my outdoor tomatoes all seem to be coming down with the same symptoms.
The leaves are starting to curl up and turn yellow. The flowers are still there and are producing the start of the fruit. These seem to be unaffected
The plants are outside and are open to the elements, and I was wondering if the wind and changeable temperature could produce these symptoms.
Any thoughts?

Dancing Homer, it sounds like Magnesium Deficiency (very common). Spray them with Epsom Salts (Magnesium Sulphate). You can buy it in any chemist or garden centre. Dissolve 3 teaspoons in a pint of water and spray the plants. Continue daily for a week but if magnesium deficiency is the problem you will see improvement from day 1.

Yes it could be.
It could also be the c*** weather we are having!

My Gran used to have the stuff in the kitchen. I was always to afraid to ask what is was for.
