I have tried it both ways adding an hole and just using the hole thats provided. Suprisingly the hole provided works well with a 70/30 mixture. I think anything over that needs an additional hole. But to my amazement these cartos work very well.
I fill my carto fully first. About 30 drops or so, then assemble the unit and fill the tank. I have been using the same carto for going on four weeks.
You may want to swap that carto out Brutha, dissect it and check out what your vaping inside of that bad boy, you may be likeonce you see it. just saying,,,,, Cartos are cheap, no sense in using one that's all burnt up it's gotta be effecting the flavor of your juice after 4-5 days Minimum. Take a pic for us if you do it to please, like to see what it looks like by now.
