Squat & Deadlift check

[Pyrao]

Noob lifter here, been doing SS for about 5-6 weeks now. Thought my form was good until I hit about 60KG on my squat and my erectors started hurting, specifically my left after a squat session I really hurt my back and took a week off. Back at it now and been working on flexibility (desk jockey here). After squatting they seem numb for some reason, unsure why. Probably bad form. Any tips to fix my squat would be appreciated. I also need some help with my Deadlift too, not quite sure if it is right. Also my reps are messed, I did 6 on the second squat set and 4 on my deadlift. Sorry about that, I usually don't do this! I understand there are loads of bumps with my form so some expert critique would help me iron them out!
Any help is really appreciated.

Thank you very much,

For the squat, you are allowing your spine to flex and extend under the load. While it is not terrible, it may be enough to cause some discomfort. Also, you are tentatively searching for the bottom of the squat. My suggestions:

• Take a big breath in and get tighter. Do not allow your back to unlock. Keeping the knees out will help.
• Don't lift your chest out of the bottom. Drive upwards with the hips.
• Find the bottom quickly and confidently each rep and then come right back up.
• Get some weightlifting shoes.
