I haven't started DIYing yet, but I have been studying up on it for a bit. I do have a question that I haven't seen posted yet. On nic level of the base solution I see that many suggest to start with a low mg level and as you master the techniques then you can go up. I am looking at wizard labs pg/vg mix of 18mg which for most flavors I would make I don't mind hovering around 12 to 16 mg of the final mix. What is the advantage of working with a 100mg nic base and then cutting to the idea nic level versus buying the 18mg nic level solution and just adding the flavors to it which at 10% to 20% flavor would produce around that final nic level. May be an easy explanation, but one I am stumped on. Thanks for the help.
