Tomato plant problem

[Hillbilly]

I have 11 tomato plants of varying types and breeds in the greenhouse. They are all planted in containers with organic compost and fed once a fortnight with organic feed (shop bought)

They are approx 4ft high now and producing fruit.

Its been really hot so yes, they have wilted a few times and after testing the soil, need watering once if not twice a day (before sun up and after sundown). I make sure the greenhouse is ventilated during the day.

I have had a few yellow leaves near the bottom but have removed them and until 2 days ago, didnt have a reoccurence. They have been growing fantastically well.

However, I walked in this morning and its a fair bit worse. I am pretty sure its not early or late blight. Some of the leaves have lesions but some don't but on one side of the greenhouse, the plants are now mostly yellow to about half height!

Any ideas you guys? Verticullum virus?

PS this should have actually gone in fruit?

Any chance of a picture? That always helps. My instinct is to say just remove the yellow leaves, it could be the heat/drying out/normal turning yellow of leaves mixture of things. Hope so. Try a Google image search for tomato virus etc maybe.

I'll post a pic tonight as DH has got the camera..

Hope its normal. I have several recipies that require a glut of tomatos
