I recently bought a Norway Spruce, Picea Abies sapling in a 33cm pot and the instructions say i can feed it using baby bio??.. I thought that food/fertiliser was for houseplants?.. if not what food/fertiliser can I use to keep feeding it on? Thank you

One of the more convenient things about plants is that they can't read. :)

Bay bio will be fine for your potted Spruce, although it doesn't need feeding that often anyway. The formulation of Baby Bio, in NPK terms, is 10.6-4.4-1.7, which means its much higher in nitrogen than P & K, and nitrogen is what makes good leaves. You don't have to use baby bio though, you can use any plant food that has a similar NPK, or a balanced NPK such as Growmore (7-7-7), but don't use things like tomato food or anything that's higher in K than N. There should be an NPK printed on the pack of any decent fertiliser...
