Help Trying to identify tomato disease

[onion man]

hi all
i have grown 10 tomato plants this year as every year.
this year they were doing fine as usual no problems about 6 weeks they just stoped growing in height then the leaves started curling and turning a purple colour as photo shows
i have them in 15 lt pots and feed on Richard Jackson's Flower Power Premium Plant Food
has any one any idea what the problem is ?

Pure guess hormone damage, maybe weedkiller or something similar.

I suspect the same.

Can you show a pic of the leaves face on as it were, plus the stem further down?

in the allotment next to my greenhouse they had potato blight
hope this helps

Purple can be cold and also a dificency - I forget which one. Several of mine have been purple this year.

What had potato blight? It could be that but it usually shows in the stems. However this year, some of mine looked like this and didn't get blight, just looked rough as anything and hardly produced fruit; and some didn't show signs of blight on the stems but did in the fruit. I don't think the leaves are distorted enough for it to be herbicide damage.

Been a weird year.

I am putting it down to 2012 being a bad year and just binning things that aren't growing well.

You have botrytis at the base of the top truss, which is why that one has withered.

Where the leaves meet the stem, there are brown lesions: that bit looks like botrytis to me.

Can you cut the stem? Have a look inside the stem and see if there is brown/red inside (indicating a wilt of some kind)

snap, again
