I have quite a bit of juice that I like very much. It is a 70vg/30pg blend. I have come to the conclusion that I am more than likely sensitive to PG. So I was thinking instead of wasting this perfectly good liquid, I could buy some 100% pure unflavored VG and mix/add to it to make it 85-90% pure VG. Would this work? If so, how would I go about measuring to get the correct blend? I'm thinking of making 30 or 60 mils at a time. Thanks if anyone can help me with this, as of right now, I cannot vape any juice I have.
