Blight?

[Scoot]

I asked this question a few weeks back and someone said it could be early blight. It seems to have spread more now so was just wondering if anyone can confirm please.

What colour are the stems? Brown stems are usually a sign of blight. If it's only affecting the leaves, just cut them off.

I asked this question a few weeks back

If the plants are still there, then it wasn't late blight.
Blight makes them collapse and look like this after a few days.

Nah...stop worrying- just pick off the leaves and put them in your household waste- not your compost

Not blight

[solanaceae]

Looks like some nutrient deficiency to me.

[Scoot]

There's quite a few of the leaves looking like this so I'm not really wanting to pick them off.

[Bigmallly]

Best take them off so as not to pass any diseases onto the rest of the plant. They won't be doing anything useful to the plant anyway.

Looks like a magnesium deficiency to me.
I sounded all knowledgable there for a moment didn't I?
I should explain;

I have a very similar affliction on my potato leaves, again, no sign on the stem.
I asked a very successful plotter on my site who should me some pictures in an old book and we identified it as magnesium deficiency.
Yellowing leaves with a profusion of small, irregular brown dots.

Most of my outdoor tomatoes are not looking great - I've given up worrying about it...

Sweet Aperitif


Marble sized fruit, spindly plants, spots on leaves.

Sungold


Spots on leaves (they always do this although usually a couple of weeks later than this).

Garden Pearl


Lots of yellow leaves (the Totem behind look rather better).

Belle


Looking cold despite more protection than the other varieties

Roma


Foliage rather yellower than I would expect.

The Shirley (usually rather more prone to cold than some) and the Totem seem to be coping best with the conditions.

Ditto Pene, yours are identical looking to mine.

It hasn't been cold, temp wise, down here(always 20 and above, not below 10) so I've been a bit confused as to why the growth should be so anemic, but most of July has certainly 'felt' rather cold (windy and not great amounts of sun).

I thought there could have been a deficiency of nutrients in the soil as I decided to use last year's compost and possibly hadn't used enough fertilizer, but now I'm thinking it's more likely they have 'felt' the cold and this is the reason they are stunted and/or not taking up enough nutrients. Got some 'tomato food' now that includes all the trace elements just in case, and the weather is cheering up now so hopefully they will spring back into life!

Magnesium eh? Anything I can feed them which contains magnesium?

I gave them all a good feed yesterday with my tomato fertiliser so they might pick up.

Well, all the leaves that were affected have been removed.. Left them looking a bit bare. I'll keep feeding them with tomato feed and some general feed and see if that picks them up.

Am I right in thinking this is blight?

We've had three full smith periods here in the last month so I knew there was a risk. I was told this morning that we've had blight on the allotment site so went to look at my potatoes and found this:





Those brown withered stems were potato haulms last week. They actually didn't look too bad a week ago.... Haven't really managed to get to the plot for over a week due to being very busy at work, just a couple of flying visits to water at 6 am on my way home from work in a morning and half asleep.... so they may have been like that for a few days.

Am I correct in thinking that they have been blighted?
