Just got me shipment today and ready to start mixing. Originally I was thinking I would mix separate components of my Nic base, my PG, my VG, and my flavors for every batch. Thinking it through this seems dumb and time consuming. Shouldn't I just make a larger batch of my target nic/PG/VG formula and use that as a base to mix flavors with? I'm not saying to mix all three big (500ml) bottles together from the get go, but maybe a medium size, say 60ml. I understand I may want to change up my ratios at some point but am I making a mistake here by going this route? Don't want to start off on the wrong path. pre-thx for help.
