Try curling the wicks inside the cup like i did in the pics above. I've been using that same build for 4 days now, one of the longest lasting cotton wicks I've had yet, and every tank i filled gets vaped dry, no dry hits and barely any leaching/discoloration. But some stuff is just frustrating. Like i said before, I was about to unload/trash this thing quick before i tried that. It's got it's issues, but i do love the vape I'm getting off of it. Good luck.
