Hi guys just about to make 4 new juices and my very first diy mixes but have left it for now as the only thing that baffles me is on the calculator i dont know what to put in for the concentrates. I dont know if they are pg, vg or what percentage. i have looked at the bottles and 2 mention vg, flavourings and water and the other 2 mention flavourings and water but not pg or vg. any tips appreciated thanks
