Knees caving in and weak deadlift

[piruvatas]

Hey Rip,

I'm 21, 187cm, bodyweight 91kg and slowly going up - that's about 6'1" and 200lbs.
Here are my latest numbers:
Squat 130kg 5 5 4
Deadlift 132.5kg x 4
Bench 88.5kg 5 5 4
Press 53.5kg x 5 x 3
Power clean 55kg x 3 x 5
Chins 8 5 5

This is the first time I have missed a squat.
I microload the bench and the press, I sleep 7.5 to 8.5 hours a night and I averaged 4000 calories per day this past week.

I have two questions:
1. How can I fix my knees caving in during heavy squats?
2. What can I do about my deadlift being so weak compared to the squat? I love the deadlift and I want to be better at it. I read the recent Santana's articles but didn't find anything obvious I could fix.

Any general tips are appreciated too.

Three sets of squats
Deadlift forgot to put a belt on.

Rest between sets?

Rest between sets?

10-12 minutes between squats.

Work up to a heavy weight you can keep your knees in perfect abduction, do 3 sets across, and go up from there. Never accept any rep that shows knees valgus ever again.

On it, coach.
