It’s 3mg, not sure if it’s vg or pg based. I think it’s not the juice it’s the something wrong with the tank. Can you rotate the glass tube (without reaching a holding point) when it’s assembled and on the mod?what nic shot are you using with the kustard. its 70/30 with zero but it depends which nic shot youve added as it will make it thicker if its vg based or thinner with pg based. im using 50/50 and still no leakes.
