Tomatoes -- aaagggghhh! is this blight!?

[Veggiemite]

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?

It looks like early blight to me, not nearly as bad as the usual 'late blight'.
If you remove all effected leaves the plant may survive and fruit ok. If it gets on the top leaves then I'd remove the plant completely.

Watch the stems too- if it gets on there I'd chop off the top growth before it travels down to the spuds

[seasprout]

I'm saying possibly not.
Because the stems look ok.
Don't panic, just keep feeding, and keep a watch.

There are so many types of spores around in this weather!

One thing I would advise - pick off any partially ripe fruit. It will ripen fine indoors off the plant, but if blight spreads onto it it will rot.

Great advice from Penellype ^^^

It isn't late blight, you probably won't have to ask when you've got it, it can devastate in a short amount of time.

I get what you've got fairly often, it turns up on leaves that are old, near the bottom of the plant. Also it seems it could be deficiency related from looking at your photo as there are purple patches there too along with the brown ones. (probably due to growing in a pot and therefore not enough trace elements available but nothing to worry about).

Wish tomatoes really did produce spuds as well Those tomtato plants don't really work despite the blurb

My Tumblers always have a few blotchy, scrappy leaves on them, don't think it's anything to worry about just yet. I just take off any leaves that look really bad.

Well spotted Thelma!!!

Yeah. Also if possible put unripe toms in a draw with a ripe apple if you have any(my early apple tree isnt fruiting this year after a bumper crop last year and heavy trim over the winter so Ill struggle with this).

Also having trouble with possible blight but dont know if it may be lack of magnesium or nitrogen from what Ive read. Only hitting 2 of my tomatillo plants, the Grushovka bushes look great.
