All my tomato plants are not thriving and the leaves are losing colour and withering away. Would this be too much water, or not enough or maybe too much direct sunlight?
A few more details would help along with a picture if possible. Are they in pots or cells ? In a propagator? etc.
Can't have too much light yet... I'd suggest water ( too much)
Yes, yes and maybe. :o
Sorry no digital camera so can't put photo up. The plants are on windowsills. Some of the leaves had a white patchy appearance before they withered and dropped off.
I would suspect too much water.
A windowsill is not an ideal place for seedlings as although the light levels are beneficial there are huge variations in temperature between day & night which can sometimes cause problems.
So many reasons-getting warm and then chilly,and yes too much/not enough water.
But as I posted on another site -never worry until they are dead,as long as the top is growing they will recover
Are they getting enough food?
What size pots are they in?

I'm noticing this this year. A couple of weeks ago I had a tray of peas on the windowsill; Kent Blue were next to the window, and were very slow to come up. This time it's beans, and again the ones next to the window, Major Cook, are very slow. Both times the rest have been fine.
As well as size of pots (hopefully not too small - at least 3"?), presume you've used the correct sort of compost, have you also checked for bugs/pests? (occasionally I've found a small slug at the bottom of pots). Checked under leaves, at the bottom of the pots, those sort of places...
Mine did exactly that when I left them in a cold spot overnight. Lots of white patches that never recovered even though new growth was fine..
