So I've only been getting a few days out these coils, while others are getting weeks. I have no idea what I'm doing wrong. I use good quality juice, mostly 50/50. I'm vaping at around 26 watts on a Hanna clone. After a few days they get very gunky and pieces of charred juice come up into the mouth piece. The vapor production decreases as well, but the biggest problem is the decrease in flavor. After two days of use I have two coils that are extremely muted in flavor. I have a peach in one and a creme brûlée in the other and you can barely taste any difference. In the first day of useeverything is extremely flavorful( almost too good because the juices are so sweet). The brands of Juice range from nicoticket/itc/jimmy the Juiceman and are 6 mg. I chain vape during the day, but then go for long periods of time without vaping. I've tried to wash the coils in warm water but have had no luck. Any help would be appreciated. I'm running out of money =(
