Lalesa what may be wrong is there may be some primer dried in your attys.
Mine did the same thing untill all of the primer was gone even turning my ry4 a wierd reddish brown color in the carts.
The best way i've found to clean mine is to get a small pot and fill with water and heat on the stove untill it just starts to boil.
Then I turn it down untill just below simmering and using a long pair of tweezers swish the atty around for about 10 seconds, rinse in warm water at the sink and blow out from both ends when it cools enough, repeating 4 or 5 times untill clean and blow out real good with a paper towel in it to dry. then I draw on the atty attached to the battery for about 3 or 4 seconds to do a dry burn. Reprime and it should vape right.
I'll give that a try Charlie - Thank you. I've washed them once with no difference but I'll try what you suggest and see if that makes a difference. I hope it does, I'd really like to use them AND like them.
