Tomato - cold weather damage

Symptoms

Tomato leaves curl up, pollination is poor and the fruit might develop scars and holes.
Find it on: tomatoes
Time to act: spring, summer, autumn

Overview

Sun-loving tomatoes can suffer outdoors during spells of cold weather, with ideal temperatures from 18-24˚C and no lower than 13˚C. If it is too cold there might be poor pollination, curling of leaves and the fruits might be scarred, with holes.
Solution
Tomato leaves curl up, pollination is poor and the fruit might develop scars and holes.
Organic
Don't plant out tomatoes until temperatures in early summer have risen, especially at night. If in doubt, plant the tomatoes into generous-sized pots so the roots have plenty of room to grow and stand them outside on warm days, bringing them indoors when the temperatures drop. By late-June it's usually safe to leave them outside in a sheltered, south-facing, sunny position. When temperatures dip again at the end of summer and early autumn, give tomato plants overnight protection with horticultural fleece, which should keep them safe until the first frosts.

I have some young tomatoe seedlings which I am bringing on in an unheated greenhouse. I also have some young tumbling plants & standard plants bought from a garden centre which are much further on than my seedlings. however, I have notices over the past few days that they are all beinging to look as though the leaves are turning yellow & some early flowers have died on my tumblers. Could this be that the cold weather is affecting them. The temperature in my greenhouse over night has been around +1-2 deg C
