You could be right. Burn those leaves/plants and get some new plants - there's still time.

Don't think that's blight from your pic...........looks like some sort of deficiency to me....what are you feeding them with...if anything?

See what blight looks like here to compare with yours

Looks more like this to me..but not very clear

Magnesium deficiency causes yellowing between the leaf veins, often more noticeable on the lower leaves.  control with two foliar sprays of Epsom salts (54g per 4.5 litres water) at fortnightly intervals.

Don`t panic , i think a tablespoon of epsom salts per plant will cure that.

It looks like a lack of magnesium.

I think its too early for blight ... and that it looks like Magnesium deficiency.

Like the others, I agree that it doesn't look like blight - also, I don't think there have been any blight warnings in the country (would be worth editing your profile so we can tell your location) - there are very specific temperature / humidity conditions required before blight is probable

Thanks for replies and hope that it might not be blight...i'm feeding with tom food, not that often TBH just started as they have just started to set fruit. There are hundreds of flowers on them as they were planted mid Feb. Its only affecting the £ makers and cherry toms, the bush varieties all look fine.
I've segregated them this afternoon (sick ones inside house) just in case and have sown an entire load of new ones on the other side of the garden under cover.

if it's not blight, can i ask opinion, do people keep toms in several locations. I have lots of windows in the house that i could grow some on. It seems a bit foolish now to have all my eggs in one glass basket!

I have had that on the lower leaves of my toms in the past - I agree with others - Epsom Salts or a liquid seaweed-based product containing trace elements should correct it. I'm trying Maxicrop seaweed-based liquid tomato feeed this year and have just started feeding my toms and so far, they look good.

  Glad you never burned your plants earlier    They should be fine in  few days with a dose of epsome salts, as suggested

We've had a full smith's period (the right conditions for blight) where I live.

This is early blight on a tomatoe

Blight is a fungus that likes warm moist (humid) conditions. It is a bit early for blight anyway, and I would suggest Yorkshire - the windy bit, is probably a bit cool (still) for blight. So do as the guys say and give it a dose of Epsom salts and see what happens. In any event ES won't kill it. So have that wine anyway and cheer up!

Hello,
I would agree with the diagnosis, but would question the amount of Epsom Salts prescribed, if I may. Are you sure a teaspoon per five-litre watering can, which has always worked for me, isn't enough?

[8doubles]

I grow my toms using ring culture , water from the base feed from the top. I sprinkle the dry epsom salts on the top of the compost and normally one application does the trick.
If you water it on the leaves 95% runs onto the compost anyway 

I also tend to be ruthless with thinning the leaves, if there are too many, ones in the way or damaged (if they are mostly yellow they are not working ) they get taken off.
Improve the air circulation and let the sunlight in and you get less blight.
