Okay, first step to learning more-- you can read your coil's resistance ON the coil (it's printed in tiny letters) as well as (usually) a manufacturer's wattage recommendation. That's a guide, you can vape below it and many people do, vaping HIGHER than recommended however, will likely shorten your coils life.
If you are sub0ming (less than 1.0 resistance but most "cloudy" setups are lower than that) at fairly high wattage, you would do better with lower nicotine than a smaller setup, which isn't providing the same "volume" of vapor than a direct lung setup (sub0hm setup), which is typically vaped at lower nicotine. Many sub0hm vapers are vaping in the 3--9 mg/ml range, while MTL vapers using higher resistance coils are often in the 12--24 range, or even higher.
You tailor your eliquids to the type of vape you are using and then fine tune from there, as everyone reacts to and vapes a little differently. Even length of inhale can make a difference. If you are in a "safe zone" for your vape, and if you aren't getting nicotine overload and feel you are vaping "enough" you are probably fine.
If you are getting headaches, dizziness, etc., then you can look at lowering your nicotine and vaping less and/or both. If you aren't having problems, then the number you've arrived at (by whatever process) is probably fine.
But, knowing your own coil's resistance and how much wattage you are using would probably help you figure out where you "need to kind of be" and those coils will need to be replaced at some point so knowing what you are USING is kind of important, so you can continue vaping successfully.
Many tanks come with a variety of coils, designed to be vaped at different wattages, etc., so if you got a kit, you need to know what resistance and type of coils came with it, as there can be wide variations in coil type in some setups. Etc.
