Bio bizz is a great line of nutrients...I use there product from time to time.....yet for me it lacks fish hydrozalate , and the mixture of guano that IMO is what you will need to grow as big of buds that you can possibly get in an organic grow. Bio bizz active ingredients are molasses and kelp...which is what I use as my booster in conjunction with VITAL EARTH nutrients . The second reason youre only getting what you got is your 600 watt light. Unless you have your light 12 inches away , your 600 watt ain't bear you what a 1000 watt could .
