tomatoes looking ill, with photos. help?

They look as though they have gone blue with cold to me.  They will grow out of it when the weather warms up.

sorry, i forgot  ;)to add, they are in the greenhouse, which has got very hot recently,

Don't worry, they will recover. Mine all went like that and i feared the worst. They have caught a chill over night.

It is amazing the power of recovery that tomatoes have.  I have found that provided the problem is just environment, they usually receover when conditions pick up.

I decimated my tomtoes this year by a combination of forgetting to open the greenhouse door, and forgetting to close it.  Earlier in the year I put them out when the weather was getting warmer and accidently cooked them inside the greenhouse.  I then had the opposite problem by leaving the door and vents open during some heavy frosts.  I stripped all dead leaves off which left the main stem about 2 feet high bald with no foilage at all.

Since then they have sprung back to life, flowered and set fruit.

My suggestion (admitidly from a careless gardener) is strip off all dead/dying leaves, drop the watering right down for a while and improve the temperature they are in.  Just don't forget to give them air when it gets sunny
