5ml Artemas Locking DCT tank not producing as much vapor

[vapourskull]

Recently bought an Artemas locking DCT 5ml tank and I LOVE it! The first few days I used it, it produced loads of thick vapor. Now however, I'm having to pull on my evic for around 9 seconds to get a decent vape.

I used 20/80 juice, a 2.5 ohm carto, and set my device at 4.4 volts.

Can someone enlighten me as to whys tanks not producing as much vapor? Could my carto have dried out and I need to re prime it?

The carto drying out could be an issue, especially since you're using 80% VG. How many holes does the carto have? 2 or 3 holes are recommended for high VG juices. (PS: it's not the tank causing the problem, it's the carto)

My carto has two punched holes. Surprisingly enough my juice really isn't that thick....

So if my carto is dried out do I re prime it completely? Like 25-30 drops? Or just a few? I don't want to flood it...
