Yo,,
Im on my first grow too, and using bio-bizz nutes,, what bio-bizz reccommend for best results, using all three nutes, Basically you mix bio-grow (veg nute) 1ml per litre... bio-bloom (flowering nute) 1ml per litre ((as weeks go on you increase this)) and top max 1ml per litre ((again as weeks go on you increase this)) there is a chart on there website that will help you,and tell you exact amounts to put in as weeks go on., if you are goin to go down the bio-bizz route you definatly got to get top max i was considering jus mixing veg and flower nutes but top max helps carrys all the good sugars and resin to the buds and maxismises them,,,, but as for results i wouldnt be able to tell as its my first time using them but for the veg nute that worked well ( a hole lot better then mircale grow what i started with) hope this helps good luck
