I have a dual coil set up on my rda, it was built by a local vapor store. I've been using it for 3-4 weeks and have changed the cotton numerous times. Lately I've noticed that only one side of the cotton is burning the liquid. When I dry burn the coil, one lights up faster than the other.
Could something have happened when I changed the cotton?
Is it time to rebuild new coils?
What else can I do to troubleshoot this issue?
