i have 36mg nic with 100% pg base. i also have vg, but no pg yet. it's on order(wizard labs) cause tractor supply was out of stock. i have some tobacco flavors, peach,mocha and what not(also from wizards). the ejuice calc keeps giving me a neg pg. is there some way i can get a 24mg juice with no pg? or should i wait for the pg.
