Cordon Tomato plant pruing & growth query.

In my greenhouse I grow my Tomato plants as cordons, tied in to a cane, pinched out when they reach the roof or the top of the cane, side shoots removed.
Now the question I have, and the reason for asking it is:
Am I being too fierce with my growth restriction?
Because the fruiting trusses have started to grow from the tip as vigerous new stems.

Morning Peter, i think that some varieties or more prone to this than others, i don't think it is down to you being very fierce.
But maybe it could be down to the plants being grown exceptionally well and full of vigour!

Hi Peter,
I have had this in the past and have put it down to over feeding especially with too high a nitrogen content.
This happened the year that I changed the soil in my greenhouse and put 12" of manure in the bottom just 18" below the surface.
With regards to pruning I take out the side shoots up to 6 trusses and then let them get on with it after that. This is with Gardeners Delight
but with all the other varieties I stop the plant after 6 trusses.
With the GD I have actually picked a handful of small, but beautifully ripe, Tomatoes on Christmas Day. Somehow, as the plants get older they seem to become hardier because by Christmas (here) the temperature must have been well below freezing on many occasions.
