Is the puddle due to you over dripping?
make sure your wicks are touching the deck it could be possible that they arent quite touching and soaking the
juice up which would lead you to think you need to re-drip which will in turn over fill the deck and allow the
juice to seep out of the airholes, do you get a slight gurgling aswell?
I have the same rda but i didnt use it much but when i did i used 3mm id coils so that there was lots of cotton down in the well, and also make sure your wicks arent cupping the top of the airflows orelse that will also cause leaking.
