My eleaf lemo 2 is leaking which isn't much but at times it does leak a lot, especially around the air flow chamber. Seems like I'm doing everything right, no idea how to stop this leaking. Also after I fill my tank the juice will be clear (or whatever color the liquid is originally) but after a couple puffs of the juice sitting for a couple minutes the juice will become discolored on the bottom of the tank toward the juice wells. The discoloration is dark and begins at the bottom slowly dispersing through the juice. Does anyone else have this problem? Thanks so much in advance.
