Cucumber Pepita

[Bluemchen]

Anyone know how big these cucs should grow? they're currently about 10cm, and seem to be growing banana shaped! Is this normal?

I haven't done anything to the plants except tie them in - should I be doing anything to maximise harvest?
Thanks

Pepita F1 all female cucumbers, produce mini size cucumbers of 20 cm long according to the seed packet. I am picking mine at about 15 cm as there are so many of them.
