Please tell me this isn't blight!!

[TattyJJ]

So a few days ago i noticed a few leaves had gone a bit brown round the edges of one of my tomato plants by the greenhouse door, but thought nothing much of it.
Then today i notice almost all the tomato plants in the greenhouse seem to have leaves that are going brown!
Really hoping this isn't blight and something not to worry about, they have only just started producing flowers!

Oh dear Tatty, I really don't want to tell you it's blight ....... but it looks suspiciously like it ...... I'm no expert though, but someone who knows more will put you right .....

Do you have any brown marks on the stems? I'd cut those leaves off,it looks a bit like a few of my leaves where an insect has been feeding,can you see any little bugs on the back of any leaves?

[veggiechicken]

I wouldn't like to say, but would remove all the affected leaves and keep watch on the stems.

No sign of anything on the stems, just on the leaves and mostly round the edges. Also no sign of any bugs...
To remove all the leaves that have some evidence of it would be to take of a LOT, as in over half!

I don't think it's blight, are there silvery grey halos on the underside of the damage ? Unfortunately blight morphs year on year so this years symptoms might not look exactly like last years. I'd go for damp climate interspersed with brief periods on intense sunlight; no wonder the plants struggle to keep up.

and tomatoes can stand to lose a lot of leaves...it letin light to ripen fruit and aids air circulation.

I remove all leaves from the bottom foot or two and lots further up during the season for those reasons so I reckon yours will be okay with it.

Are the plants indoors? I have marks like that on some of the tomato leaves in my friend's greenhouse, and I think its where water has dripped off the glass onto the leaves (the greenhouse leaks a bit). I've just nipped off the leaflets, not the whole leaves.

Blight on tomatoes is characterised by rapid spread and blackening of the stems. Once symptoms show there is no way to stop it. Therefore I would think you have nothing to lose by nipping off the affected leaflets and keeping a close eye on the plants. If it starts to show as black marks on the stems then the plants won't survive and I'd be removing them at that point.

I don't think it's blight either, I've noticed that people often get understandably panicky about blight and assume all marks are the first signs when actually there are loads of other things toms etc can suffer from. Have know people dispose of entire plants before ensuring it actually is blight.

It doesn't look like blight to me but I'm no expert.

We lost one of our potato plants in the last week due to blight, the stems and leaves all turned black within a couple of days, thankfully we spotted it early and got rid of the affected stems and the others in the same pot seem unaffected (fingers crossed)

If the stems go black that's a sure sign but until then I would look at other causes, this ridiculous weather recently is making all our plants suffer.

Have you been feeding them?

[TattyJJ]

I have removed the worst of the leaves, there are no halo or slightly transparent bits, and no yellowing at all. They just seem to be turning brown and crispy from the edges inwards. Have been feeding them every 10 days ish with tomato feed, and had some epsom salts too.
I have 4 tumbling toms hanging from the roof and they are all totally ok, also another 4 outside sowing no ill health, same goes for 5 gardeners delight in a large blowaway.
Really hoping it isn't blight, time will tell for sure...

Fingers crossed!

[jonny the plant pot]

I wouldn't say it's blight I'd say the plant is channeling energy elsewhere

[Nicos]

Have a look at this.....

Is it Early or Late Blight, or Septoria?

[ESBkevin]

As suggested by Penellype it might just be water damage, in any event nip off all suspected leaves and dispose of them well away from the growing area in a hot compost bin or disposed of off site.
