You're right, it's absolutely the wicking. I just looked at my bottles again and the tank that works fine is the one with 20/80 liquid in it, and here I thought it was the tanks and not the liquid. Well, at least now I know what the problem is. I'll just start ordering 20/80 or 30/70. I just wish I hadn't just ordered $70 worth of 100% VG liquid. Oh well, live and learn I guess.
You can thin the 100% down with a little distilled water or unflavored pg. Just trying to keep you from wasting liquid.
