I did notice that you did a lot of warmup sets Saturday. You did 7 sets then your top weight (75kg)for your light day. One of my last heavy squat days I only did 4 warmup sets before my top set at 93kg. Unless you just want to do that much volume you might try less warmup sets. That's probably why you are sore. The more total reps done is hard on us old farts and takes longer to recover. I know everyone is different. Just a thought.
I've had a problem with my left hamstring a few times. It always seems to happen when I'm sore from a previous sqt WO. I like to do some higher reps SLDLs to heal it up.
