I think the yellowing is from a magnesium deficiency, I was about to feed them just before I noticed the stem (that blackened part happened over the course of two days), I haven't needed to water them at all really so didn't get round to feeding.
I don't know whether it's a magnesium deficiency, Leggi, or just the beginning of the end for the foliage. Here's LB on a young plant with failing foliage:
I've just been to have a look at the 3 Marmandes with the black patches on the stem - they don't look any worse than they did this morning. As I said I've moved them over to the other side of the garden and the foliage looks really healthy at the moment and the fruits look good. I'm thinking that I might just reprieve them for a bit and not bag and bin them just yet - what do you think?
If they're well isolated it can't hurt to keep a watching brief. If it's LB, it will spread across the plant within a week or so.
Well, they don't look any worse this morning than they did yesterday - still black patches on stems, but no blight on the leaves that I can see. They had their first dose of Tomorite (well Notcutts version of) yesterday as the second trusses are setting. They're still as far away from the others as I can get them - they all still look fine - so far.
Fingers still very crossed.
Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.
There have been occasional patches of blight on the leaves - some each day, sometimes a couple of times a day - I've been inspecting three times a day and snipping any infected leaves off and bagging and binning them. Then we've had three days now with no blighted leaves but the black patches appeared on the stems
Still only affecting 3 of the 6 Marmandes and nothing on the Red Alerts.

Oh! Should have read that a bit earlier - one lower leaf with blighty patches on three leaflets on one suspect plant, another suspect plant had one small blotch on one leaflet. Both were scrunched up in a plakky bag and binned (unphotographable) - I'll photograph the next ones I find.
It's strange because when I checked at around 6.30 this morning there were no more patches but 10 minutes ago there they were, and that has been the pattern over the last week or so. Nothing early on then lataer in the day these patches that look exactly like blight appear then after I've removed them nothing more most days.
When we had blight in the last garden, as you've said, the plants collapsed within 3 or 4 days.
I'm beginning to wonder if it's Early Blight and I might be able to keep it under control. What do you think?

It could well be as the majority of the plant looked normal. Do you have any advice on how to grow toms in gardens that have had LB or should I give up trying on my patch?

Odd that there's nothing showing on the foliage. LB usually starts on the leaves.

Very strange. Post a photo of the infected leaves before you bin them next time.

Not terribly clear I'm afraid, but another blotch on a leaf this afternoon - the blotches on the stems haven't changed in two days.
