could be, this tanks really runs little cotton wicks, i use it with salts so i never run a full refilled tank, thats another thing to consider when wicking, the exact liquid retention you want or aim too, i really use thin wicks and fine coils, they are so tiny and also the mtl wire seems a bit like fragile, i will try to rebuild mine since i like to try a new mixed salt juice i will be using, so i will try to attach a pic about my wicks!
tell me a bit more about your tank, wicks material, coil and juice you use... to try a bit more to help!
Regards,
