Why have my tomatoes gone like this?

Some are going funny at the top?

it's too dark and cold for them now.
take off all good ones now and take them inside to ripen.

Definitely too cold for them now. It's been such an odd year for plants. One of my tomato plants did amazing and the other one just died.

Have taken the ones without the marks on and put them on a windowsill. Thankyou.

Is it the same for the peppers?

Yes mine are like this , first time I've grown them, I have a few in a bowl now but there are some I will bring in the either ripen or roast and freeze for soup .
The manky ones will be a shame but next year I'll be more prepared ,

My tomatoes and peppers live in a polytunnel. They are feeling the cold so outdoor ones have probably had it by now.

Bring them indoors if you can.

That could be a touch of blight on Toms as well. So don't be surprised if the ones you bring in suddenly go funny as well (if they don't they are fine to eat). It's too cold as well, if you bring the peppers in it might help prolong their life

They have blight, it’s a common disease on tomatoes. You need to get rid of the plants asap so reduce the fungal build up that can remain in the soil for a long time and impact future years crops if the conditions are right.

Notwithstanding the fact it's October, that looks like tomato blight. Dig them out and burn them.

@RosesAndHellebores Why “notwithstanding that it’s October “?

The temperature. We've had two frosts already in the SE.

Does blight not usually happen when it’s cold, then?

Sorry to persist. My tomatoes are in a greenhouse, so they stay healthy during the summer. Then in October stems go brown/grey in patches, which I’ve always assumed is blight. But your “notwithstanding that it’s October” suggests you don’t expect blight in October.

Blight. Blight needs consistent warmth and humidity to get started (I think at lease 10 degrees day and night) so you generally first see/hear about it in August/September. But once it’s around it’s around and will keep spreading through your tomatoes whatever the weather (in my experience).
