Hello everyone... relatively new to vaping. Almost (not always) every time I use a pre-built Kanger coil on the Subtank Mini RBA, I end up with a distinct burnt aspect to the flavor. Sometimes it's right away, other times it's maybe the next day after a nearly full tank is gone. I've been careful to soak the cotton, have the cotton firm inside the coil with enough at the intakes, let new primed cotton sit for at least 15 minutes in a full tank before vaping, and did a few cold drags (is that what you call it?) to make sure the cotton is soaked before applying heat. I don't get this with the Kanger OCC all-in-one replacement coils, at 0.50 ohms. Any ideas on what's going wrong? (Nicotine in my juices is 6mg, 18-30 watts, same result)
