Sq/Dl form check

[O157H7]

34M, 6'5", 220lb, SSLP since late Oct 2019.
Sq 380
Bp 232.5
Press 145
DL 425
Smooth progress with only rarely failing a rep, biggest setback was transitioning from Press 1.0 to 2.0 method around the new year. Eat 4k+ cal/day. Sleep 6-9 hrs a night, depending on night.

Then I taped myself. Squat is 2-3 inches above parallel. My progress is a lie. Started Sq at 315 on 1/31/20. Here are work sets at 320 including a failure on rep 1 from 2/2/20. 7 min rest. I struggle to precisely gauge the depth from the coaching angle. Sorry about the shit light.

Set1

Session after hitting 425x5 on my Dl (1/19/20), strained a spinal erector during warmups the next session. Super painful but thankfully just a strain. Dl has been all over the place since, as I try to ramp back into where I was while resuming LP. Has ranged from 430x3x1 with gas left in the tank to repeated failure on the floor at 405. My only set of 5 from yesterday is a warmup set. Had failure on the floor of rep 2 at 405, inexplicably chose to reset in between reps which I never do. Had to shoot in portrait to capture head, feet, and close end of bar.
405x1 fail on 2, mixed grip
315x5 hook grip

Thanks for your time and consideration.

Squat stance is too wide. See the knees cave in on the last reps? That's why.
