So I bought some 70 pg 30vg liquid and it's like trying to vape water. I can hardly get any vapor and at first I thought it was my setup, but after rebuilding I tried out some old juce and bam the clouds were back. So what I was wondering is if I should head to wallmart and pick up some VG. I have never done it before and was wondering if anyone has some pointers on how much to use ext. I have $100+ in juce and don't want to mess it up. Thanks in advance.
