Very nice. A common saying around here is ohms +2 to find your rough starting point. I find that's a bit high for my tastes, maybe ohms+1.4. Every juice is going to have it's own sweet spot so there's no hard n fast rule. Start low, puff a couple times, give it a tenth, puff a couple times, etc. You'll have it mastered in no time at all.
Edit: Not to mention that I'll frequently adjust the voltage on the same juice. I like my coffee juice a little lower in the morning & I find it tastes better a couple clicks up in the afternoon. You have VV, just do use it. (Don't sue me, Nike)
I agree with this explanation.
that ohms+1.4 is a good starting point
I know a lot of people vape low ohm high volts, I tried this, all I get is harsh burnt juice.
They will vape 4.3 volts on a 2ohm coil. Holy monkey balls. I just don't get how they vape that.
I vape 2.4 ohm coil on silica at around 3.7 volts
so that is ohms+1.3
However, as Qzwald stated, it does depend on the juice.
Once you get it though, you will know it.
Another thing, don't keep at it till you think you are getting it, take a break, drink lots of Water or iced tea, not soda's,
or you will get Vaper's tongue and won't taste anything after a while. You may get Vapers tongue anyway, but it will go away with time though.
if you are going to back down your Nic, drop to 18mg, but not lower, for a while\, then drop to 12, then 8 and see how you feel about it.
You may have to go back up, But you should vape each for no less than 1 week to a month before dropping again.
Everyone is different so you will need to listen to your own needs. This is a guesstimation, not gospel.
Good luck.
