You probably didn't get it filled
How to fill a Carto
First, Take the silicone condom off the end of the carto with the white top. Leave the condom on the threaded end. Then take off the white top of the carto. If you have a syringe,(18ga.) load it with 1ml of liquid and slide the needle down the side of the carto and fill from the bottom . A few more drops from the bottle until the top of the filling starts to look “slushy”. If you don’t have a syringe, just slowly drop drop drop about 20-40 drops. (drop sizes vary, 1.0 ml is the target) Let the drops go down the side of the carto, constantly turning it, not into the hole in the middle. Every 10 drops or so it may help the flick the carto like you would a thermometer to force the liquid to the bottom of the carto. Continue until the top of the filling is “slushy” and the juice stops absorbing into the filler. If you have a drip tip, throw away the white end cap thingy and use the drip tip, otherwise pop the white thingy back in place to vape and then get online and order some pretty drip tips.
I know it may seem complicated, but it really is not
One more thing. Don't vape too long without topping off the carto or you will burn it. You'll get a feel for when you need to top off, (too warm, dry or reduced flavor) but until you do, do it often. If the filler is white, top off. If it takes more than 10 drops to get that slushy look on the filler, you may have waited too long.
