My tomatoes are about 3 inches tall at the moment and are in an unheated greenhouse although there are a couple of propagators which are on during the night so that may warm the air a bit, I cover my plants with fleece at night just for safety but last week I noticed that one of them had flopped over and was looking very sorry for itself so I just poppet it into the propagator for a few minutes and it has been right as rain ever since.
No food until the first truss is set, as @punkdoc has said. They have enough nutrition in the compost each time you move them on. Overfeeding can cause that colouring. Just light, water, and warmth is all they need just now. Any exposure to cold - wind in particular - will affect them, as they're soft. It usually creates bluey looking foliage though. If you keep moving them from the house to a greenhouse, the fluctuating temps will have an effect too. I only sowed mine yesterday.

I sowed mine a week ago and they're just coming up. No greenhouse here. By the time they're big enough to go outside it should be warm enough (with fleece to hand for nights). I'll be setting up a makeshift reflector for them on the spare bedroom windowsill, to maximise light.
Doncaster, South Yorkshire. Soil type: sandy, well-drained
Thank you so much for all comments I can stop worrying I have done them way to eairly but that is all part of been a keen enthusiast new Gardner trusses are appearing but I am thinking of removing them as I want strong vegetation first as for fertilizer it's only getting what the compost provides I will update in a week hopefully there's an improvement
Don't worry too much about them @Craig.wray - we've all been there
We get posts every year about tomatoes, and most of them are about seed sown too early, and feeding, and the problems it causes. I think they'll be fine.
The most important thing with tomatoes is to keep a consistent watering regime if they're staying in a greenhouse. That prevents other problems later on. They're best left to get slightly on the dry side before watering again. It encourages them to flower a bit sooner if they're a little stressed, as they think they're days are numbered
