I hope someone is able to help me on this. I have a ton a 0 nic juices and I wanted to add a nicotine salt base. I've found a bunch of calculators to show how much nicotine to add to make your own juices but I've only found one calculator to calculates how much nicotine to add to a pre-made bottle of juice. The only problem is that it doesn't account for the PG and VG content. The bottle of juice that I have is 30/70 PG/VG. I found a few sites online that sell 100mg nicotine salt bases but they come in either 100 PG, 100 VG, or 50/50. I want to keep the PG/VG content more or less the same (unless anyone knows what the ideal content would be in this case taking into account which nicotine salt base to get). I'm sure there's a simple answer out there but this has gotten me stumped. Any help would be appreciated!
