Tomato seedlings

Some of my tomato seedlings don't look 100% happy. They are discolouring a bit and slightly ref underneath. What is wrong with them and what can I do? Thanks

    Could be the cold temperatures are limiting the tomatoes phosphorus uptake?  I see you have them outside..

    I agree with Blue Onion - those plants look stressed. It's too cold in the UK for tomatoes to be outside.

    I put them outside during the day but they have been inside most of the time. They spent 3 nights in the greenhouse where it probably got down to about 10 degrees which I wouldn't have thought is particularly cold? :/

    Yes, it looks like cold to me too.  They don't really like going much below 14C at any stage.

    A trowel in the hand is worth a thousand lost under a bush.

    Oh ok, thanks everyone. Luckilu I've got some more seedlings just popping up and I can look after them more carefully.
