Agreed with all the above. You might want to try moving from the rear right of the tee to the front left, to help close the hips on the plant. Also stay more forward and then turn the hips back much later as you come down to plant. Your hips and shoulders are too open at the plant, so you have undone any elastic core coiling, killing core power, and also at least with the arm positioned the way it is, you physically can't get your elbow forward enough of the shoulder to get the disc in the power zone.
