What’s wrong with my tomato plant?

[Cutandpaste]

I don’t think’s going to survive :(

Argh, why does Mumsnet always load my pictures sideways? I’m not this computer illiterate, honest!

The leaves have gone yellow, at first I thought it was just overwatering but now there are brown spots on the leaves and it’s spread to the whole plant.
It’s a cherry tomato, there were six seeds in the pack, only three germinated and now two of the plants look like this.

Also, this mermaids is looking secondly wilty. It’s not going well!

Could be tomato blight, a fungus that thrives in warm wet conditions. Really no solution other than to destroy. Do not compost, but either burn or put in your bin.
Wash out the pots with disinfectant.
You could get some new plants and put them in a different place.

It's a bit early for blight. Have you been feeding the tomatoes?

I looked up bought and wasn’t sure that was it. I then found info about feeding them and I think that may be the problem. I fed them this morning with tomatorite so hopefully that will help. They are in a terrible condition though so not sure they will survive.

The feeding directions are once a week but could/should I feed them again on a couple of days?
