I ordered 3-120ml bottles of e-liquid from vapergate (sho-nuff, smurf, and Monarch). Unfortunately i screwed up and somehow ordered 0mg. I wanted to order 6mg. They offered to add the nicotine for free if i sent them back and they will resend back to me.
However to save time and shipping costs i want to make it 6mg myself. I have some 100mg nicotine here. My question is how do i determine how much nicotine to add to make 0mg juice into 6mg in 120ml bottles.
