do bottom coil heads not gunk up?

[crashhat69]

i used one coil head for a month or so and it started acting like it was gunked up so i took it apart to clean it and there was no gunk on it. why would it act like it was gunked up when it wasn't?

I have no idea. Different types of juice can have a big difference in how they affect the coils. Darker thicker juices tend to gunk them up more than lighter and thinner one. Did you do a dry burn on it anyways?

There is no industry standard for "gunked up". While there may be no visible buildup of juice on the coil, it can just get oxidized and degrade in performance. Or, the wicks can get blocked, again without an appreciable amount of crud visible.

Consider yourself very lucky to have gone a month without experiencing performance issues. Per erikbal above, many things such as juice recipe affect this.

i did do a dry burn, but i had to throw the coil head away because i dropped a few of the flavor whicks and i couldn't find them

As the coil ages the resistance loses its punch. Performing a dry burn just put the icing on the cake. Dry burning coils just shortens their life.
