@growinsmoke are you a previous vaper or smoker? There are many possible things taking place, but one of them is expecting thick smoke-like clouds.
If you heat erl to the boiling point of the actives, they can boil and vaporize just as transparent as water vapor, i.e. steam, and steam is only visible if it's very very dense. On all the optimal vaporizers I've used, the vapor is wispy, barely visible, and quite strong. At the highest temps it's more opaque and more sedating.
A lot of people come from smoking, or from cloud-chasing with VG-rich e-liquids, and are disappointed with the vapor from c-vaping. That was true even with the Magic Flight Launch Box. So they push the temp and power to make thick clouds -- and they do, but it's by partial decomposition -- into irritants and toxins. I'm using Kanger ProTank2s and Sapphires, and the vapor is invisible.
There could be malfunctions in your setup too, but make sure you gauge the vapor by results, not visuals. And of course if you're diluting the erl, take that into account, with your tolerance, and the rate of wicking and evaporation. Maybe your 3 tokes is about right initially? The way I get the MPT2 to work is by saturating the wick with EJ-Mix to prime it, as the Puff people advise too. The Erl then flows in well when warmed up, but the intial tokes are of course weak. Best success 2 ya!
