A few of the leaves on my tumbling toms have these blotches on them (see photos)
Maybe not clear from the photos but the roughly circular blotches are each made up of lots of concentric rings, like you would see when looking at the cut trunk of a tree (if you know what I mean)
I've been searching on the internet and it seems to match the photos and description of blight...
At first I thought this was a bit of magnesium deficiency the same as on my other tomatoes (alicante) that I asked you all for advice on recently. But now not so sure.
So far I've just removed the infected leaves, bagged them and binned.
Questions:
1. do you reckon it's blight?
2. should I sacrifice this one plant that's in it's own pot, to try to save my other tomatoes and potatoes?
3. is there anything I could do (ideally organic but I suppose I'd be open to other options if needs be?

Those tomtato plants don't really work despite the blurb
