Help! Why are the tomatoes in my greenhouse going brown and 'sticky'?

[peripathetic]

The growbags are consuming vast quantities of water and the autovents (supplemented by an open door during the day) are working. Tagities(???) planted alongside to deter nasties. Help!!!!!!!

Is it the actual tomato or the leaves which are affected ?

The actual tomatoes.

Sorry. it's me again. Just been to have a look - The leaves seem a little dry and brittle and the edges are curling upwards but the actual fruit that's affected

Although you have Tagetes planted around, I think the plant is affected by greenfly and it`s their droppings that are causing the problem on the toms, so as long as the toms are not yet ready to eat, give a good spray of Bug Killer underneath the leaves.

I have half a dozen marigolds in pots in my greenhouse which seems to keep greenfly off my toms

Oops just googled tagetes! doh!

It looks as though you've got the dreaded blight. Google it, and it is that, then you've got to get rid of them....pronto

Peri your tomatoes are suffering from a condition called blossom-end rot. Blossom-end rot is caused by two things; uneven watering and a lack of magnesium and calcium in the soil. The condition is especially prevalent in dry conditions, which most of us have experienced much of the summer.Remove the bad tomatoes and add about 1tbs of Epson Salts to your watering can.

Many thanks to dennisb66 and others for their responses. I am following up on your advice.
