Gooseberries

Is anyone having the same problem.  My container goosberry bush seems to have come to a standstill.  This is it's 2nd year and it is still quite small and has only started bearing fruit.  There are 4 berries which are about the size of a marrowfat pea, and they have been like that for some time.  There are a lot of leaves, which look quite healthy, should I be taking some off, and if so, where abouts?  Feeding Tomorite weekly. 

Thanks.
 

Hello David

Cannot send pic, but pot size is square - 12" internal and about 10"/11" deep.

Thanks
