So I've been trying to get better at making micro-coils in my PT/EVOD and using organic cotton. My only question is how often do/should you change the cotton wicking? Starting to get slightly different/off taste out of my PT2/mini. Is it the cotten needing a change? or do I need to make a whole new coil/wicking?
, although I do have one last question. I just noticed on the bag of organic cottenballs I'm using, it says under contents: Organic cotton whitened with hydrogen peroxide. how bad is that to be vaping?
