So I just started with diy mixing last night. I am using the iPhone e juice app so I know my ratios are right. I mixed up a batch of blueberry (pa extra blueberry) with all vg. Made 10ml and so far it has no flavor at all. I started at 20% flavor concentration and couldn't taste it, went up to 30% and still not getting any flavor. I know vg mutes flavors but I've purchased pure vg premixed juices from vendors and they all have flavor. I let it sit now for at least 15 hours now and still 0 flavor. Well Maybe not 0 flavor but deffinetly not what I expected with the extra flavor blueberry and the amour I used. Any suggestions? I also added .5ml of ethyl maltol if that matters at all. Any help is appreciated. Thanx.
