BioBizz and Advanced Nutrients, Mix is good Idea??

Yes and no. You can mix different nutrients brands of course, but if you don't really know what you're doing you could quite easily over feed on something. Biobizz, plus good quality soil, proper ph checking is all you will need. And like green claw said below, when you're mixing chemical with organic, you're eliminating the organic part of your grow. In my opinion, organic, feeding the soil and the microbes is better for taste and quality although may sacrifice a little on bud weight and yield. I have tried several nutrient brands in the past, and I keep drifting back to biobizz, it's cheaper, organic and if you feed the soil (supersoil) before hand you don't need to add a lot of liquids concentrate. The plant will take what it needs when it needs it, if there's enough food available in your soil mix. Message me if you want more info on this style of growing, it saves time and money and mistakes

Biobizz is organic and works with microbes. While advance nutrients arnt and will work against(killing microbes) if you want too you can but it's a bit of a fussy mix. I would go 1 way or the other, but that's just me.. Best of luck
