Hello, I have a Kangertech 200W and I have a problem. Whenever I put e juice in it I do not get lots of vapor, I get just a tiny bit. However when my tank is empty or a tiny bit full(With like 2 drops of e juice, not even visible in thie tank) I get lots of vapor. I do not know what to do about this. When there is no juice in there I get LOADS of vapor, but with any type of e juice(i've tried more than 5) there is no vapor production.
