What most likely causes stalactites?

Rain water percolating through limestone, dissolves and absorbs the lime/calcium. Over many centuries, this lime solution drips from the roof of limestone potholes and caverns. There is a very slow build up of calcium that hangs down from the roof, eventually forming a stalactite. On the floor, the same depositing process forms an upright stalagmite. When they both meet a column stretching from the floor to the roof is formed.
