I know there are many Q&As about tomato problems but it is difficult to relate someone else's description to what you see before you. I would be obliged if anyone can positively identify the problem in these pics.

2 of the Gardener's Delight plants in my small and rather crowded greenhouse are suffering. They are next to each other in the most sunny corner. They are planted in earth as i have done many times before. There is a possibility that some potato peelings went into the compost that I dug in. The upper leaves are becoming sparse and curled.

Could be Early blight but you say they are in the suniest part of the greenhouse and you have no shading if you have watered them and got the leaves wet it may just be scorch.
Either way remove the affected leaves and bin 'em, see what happens after that & water from the bottom if your not .

Thanks Richyrich7. The lower leaves certainly get wet but I can be sure that these upper ones do not except for dew on some mornings, but I will try as you say. I am watching the other plants but no others seem to be affected yet.

[richyrich7]

Keep your fingers crossed then, it's probably scorch.

Just like you say keep an eye out

I'll go with Richy on this one!

Come on Rich - it's not the first time.

Sometimes I even agree with gobs!

Come on Rich - it's not the first time.

Only joking matey

I can see there is a lot riding on this. The thing is, when I find out if Rich was right do I let it be known, or do I keep it as an ace up my sleeve pending future developments?

Seriously however, I see that on those two plants I must watch for either the newer or the older leaves becoming affected.

I don't buy those tasteless thing that the shops call tomatoes so I only eat them during the homegrown season. Consequently I live in fear of losing my crop. A whole year without them does not bear thinking about.

[richyrich7]

We still buy those supermarket things but I manage to eat only about 2-3 of them horrible things all year.
So I look forward to the tomato season too Bernard, hopefully another week or two should see some fruits of our labour

Even if it is blight, if you do like the lads say and removed all the affected bits, you could still have a decent crop.

I got blight badly last year, and it even got into my big greenhouse and polytunnel.  First of all I dug up a lot of plants, but the thought of another year on supermarket rubbish and I decided to keep removing the affected bits to see what happened, and the plants kept growing, and on some of them, I let a few side shoots stay on and they grew and more tomatoes came, so my crop was good, only not as good as the year before, when I froze the 80lbs excess tomatoes chopped up ready for soups and pasta sauces!  Mind you, the year before I did have nearly 200 tomatoe plants!!!! lol
