DWC Gone Wrong! need help!

Tried to do a deep water culture system. It turned out that my plant wasn't liking it, Im REALLY trying 2 get this operation off the ground but for some reason my clone wasn't taking to well to it, i have a video of my setup, i believe my water leaves wern't correct, i had the water so that it was hitting the bottom of the rockwell and bubbling at the roots of the plant, still the plant showed burnt tips and yellowing of the leaves. Anyone have any possible answers? Here is a posted link to my video of my setup!
