1) Sciatica and other radiant pain in the lower extremities is a sign of impingement on a nerve (or nerves) that radiate through the intervertebral spaces. It is not just discs that can press on them, however, a ruptured / displaced / herniated / slipped disc can all cause this. There is only one way to diagnose this. Note that depending on the nature of the anatomical change, this may be a permanent condition.
2) I note that you are still deadlifting at a significant weight above your clean. How does your back feel after DL'ing.
3) Based on your video from your clean, the problem that I see here is that your set up is wrong. Post a video of your conventional deadlift.
4) Have you tried massage (and not the nice touchy-feely massage with hot rocks - I'm talking a hard, thorough, deep-tissue massage from an MT that works with athletes)?
5) Further on your PC: as an artifact of your set-up (and the bar, as Tom notes, swinging out to clear your knees, your entire explosion is up and back. Your landing is back as well. At the rack position, the bar is back over your heels with you leaned back. Not great for posterior spinal health.
6) Note:
I find that ab work makes bad backs stay bad, because almost all ab work causes some degree of spinal flexion, which irritates things.
