I used to have that problem also...
1) (Wicking/power) Too much juice too little power, juice is being sucked up by air pressure. Little/ok vapor, alot juice.
2) (Wicking/power) Too much juice too much power, juice is being flashed boiled & 'explodes'. Air pressure sucks it up with the vapor. Alot of vapor, alot of juice.
3) (Coil position/air pressure) Coil too high, the air is coming in & up like a jet-stream? If single coil, try to move the coil nearer to the bottom airhole, but dont touch or block it, at least 1mm clearance, no more than about 2mm. Beware of shorts!
It's okay to have some condensed juice in the drip tip & some rare spits into mouth I guess. Bt if it's too much then gotta work smth out...
Just sharing experience

Hope helps somewhat

Drippers are much forgiving on the wicking & power/juice balancing part but not convenient

that thank splitting juice... try other tank rta tank. if lazy rebuild just use the occ. splitting will lesser then its rba
