So I've downloaded the e-juice calculator and I'm a bit confused. The very first line,,, Nicotine Strength E-juice. Is this the nic base I'll be using? If I buy nic in a pg base, would I have to change the default of 50%pg and 50%vg? I tried that and it wouldn't let me do it. And I want a 70pg/30vg mix, which calculates out to contain more vg than pg? I used to think I was kinda smart, but this has me a bit baffled. Any help would be greatly appreciated

I haven't actually bought anything yet, but was thinking if I bought 100mg nic base in pg and diluted it with plain vg, half and half, it would make a 50mg nic base to use for mixing... yes? Guess I didn't read far enough... thanks for the links.... now I got some MORE reading to do!
