Tomato plant Jungle

I have two tomatoes plants (Sun gold) in a grow bag in the greenhouse. They have literally grown up to and through the roof window with lots of big leaves and hardly any tiny pea like tomatoes. What has gone wrong? TY

    Lots of growth, did you feed them? The hot/cold spells have had an effect too.

    Have you been "shaving their armpits"?

    Too much water and feed can make them put on a lot of leafy growth at the expense of fruit, but you also need to pinch out the top growing tips when they reach, say, six foot maximum, and pinch out all side shoots, which grow between the main stem and the leaf stems, or as Hostafan1 so poetically put it, shave their armpits  :D

    Thank you for your comments. Yes have pinched out all the side shoots but haven’t taken anything off the top. Will try that next. Many thanks

    Yes, have fed them them too.

    Feeding should only start once a truss of fruit appears. If you feed before that, you'll tend to get a lot of growth at the expense of flowers, and therefore fruit. 
    With tomatoes, if you treat them a bit mean, they are encouraged to produce flowers, then fruit, as they think they might need to reproduce. You actively want them to produce that 'seed', whereas annual flowers need feeding regularly to produce lots of flowers, which then get deadheaded so that the plant produces more.
    Different end product, so a slightly different regime :) 
    It's a place where beautiful isn't enough of a word....
