hi hustler,im in uk too i use bio-bizz all mix soil its done me proud i also use bio-bizz nute line its fairly cheap comapred to sum nutes and its pretty hard to over feed with it so real good for a 1st timer . I start them on the grow and fish mix after around 4 to 5 weeks after they've been in the soil at 1/4 strength.hope that helps man and very good luck with ur grow if u need any help give me a shout if u want.peace
EDIT : also u can pick up a box of bone,blood and fish meal for £2 @ morrisons its great to add to the soil they seem to love it
