Doesn't matter whether it is a sponge or rockwool, both accomplish the same thing. Once saturated, it doesn't matter how much oxygenated nute soln you throw at it, a saturated absorbent medium will not take any more water in.
Your saving grace is that you do have roots out of the pellets- and if the seedling went in to this system before it had roots out of the absorbent media, I'm really surprised it lived long enough to pop out roots. If the seedling only had roots within the absorbent medium and had water piped right to the absorbent media, the seedling should be dead in days.
With an aeroponic system, the pellets should be wetted ONLY with the mist rising from surface of the nutrient soln, caused by the air bubbles from the air stone breaking the surface. There's no need for a tube carrying water to be run into the pellets.
