Hello Everyone, I have recently started mixing juice for my vape needs because I simply enjoy it and I'm broke! lol anyway I still have lots of concentrates from when I tried it before didn't like it and didn't seem cost efficient at the time any way to the point I would like to make a blue rasberry I have blueberry and rasberry concentrates(100% vg) and I mix at 80/20 for all my juice I was wondering if anybody had a good ratio to mix the blueberry and rasberry to make a good tasting blue razz I would do trial and error but I'm running pretty low on concentrates so I would like to use only what is needed Thanks in advance!
