curled up 'arms' on my tomatoes

firstly hello i usually lurk but feeling a little distressed over my little babies having curled up arms....i've googled this and can only find info on curled up leaves and i'm not sure if tom plants usually have curled up arms......I've been nurturing these little guys since mid Feb and they have masses of flowers and i've been giving all the back up plants away so i'm sure that you can understand the panic...... Sorry i'll try to pull myself together. Some of the 'arms' are curled under is this normal?
Any help much appreciated.

Hi Thanks for the reply.
Toms are in a double glazed greenhouse, it pretty warm but i ventilate it every day. They are in big pots there is a little manure in the bottom of the pots but it should be fine its from the horses in front of the house so can't be contaminated.

Its just a few arms adn they sort of curl around under them selves if this makes sense...
:-)

Will photograph them tomorrow.
Thank you

They may be taking up a lot of nutrients very rapidly. They should grow normally as the plants get bigger.

Def sounds OK to me.... I think it may be due to the healthy dollop of feed you've given them...so growing really well. Later they will stretch out to "normal".
