Hi, Im just starting out also, very simple, but wouldnt it make sense to order your nice base and the PG/ VG you like and then just add the flavour? I just ordered from Wizards and got a bottle of nic base in 50/50. I then was going to start adding 5% of my total bottle desired. I figured if I wanted use a 60ml bottle then Id ad 50ml of the 50/50 base and then at 5mls total of what ever flavour/s . Does that make sense or am I making an obvious mistake. I actually figured Id work with 40mls in a 60ml bottle just to give myself a bit of wiggle room in case its either not strong enough or too strong for fine tuning.
