I've found something but again have no idea how to use it..
EDIT: i know how to use it,it's just in a smaller pot...(it's been a long smokey night)

It's the Chempak Bonsia Tree Fertilizer -- 10-30-30

Chempak Bonsai Tree Fertiliser 100g [CHEMPBON12] at www.CapitalGardens.co.uk

I think i've found what i need but would still like to know your opinion (sorry but i guess this is what happens when you're the sites go2guy/gal)

Thanks for your time...
