Leaky flavours...

[Donald Trump's fister]

I've been mixing my own for a couple of years now but keep facing a problem I can't get to the bottom of:
Some flavours leak badly & others don't.
Creamy peanut butter & vanilla custard ones never gives me a problem. Banana Moon Pie & Strawberry Fog always do. Each recipe has between 4 & 6 flavours added.
My mix is 60/40 vaped at around 4 watts with 1.8ohm coils in a Kanger 2 MTL.
The only variable is the flavours I use as everything else is the same.
Any ideas why this is?

Erm ..... 4 watts ..... are you sure you're not talking about 4 volts ? as i dont see how you're going to get much of a vape at those watts , if at all ?

UPDATE

Using it at 6 watts solves my problem!
Thanks to all who gave suggestions & sorry for the late reply but Christmas got in the way.
Cheers
