Low back tweak

[Vichouston09]

I am 5'8" 172lbs squat: 285 3 sets of 5. Deadlift: 345 3x5 bench: 195 3x5 ohp: 120.
In my last workout I "tweaked" my back from not setting my spine properly before the lift. Everything got real tight and it made it hard to move around. I have experienced this before doing high bar squats before doing the program. My question is about how to continue the program. Do I take a few days off for the spasm to stop? Do I drop 10 pounds and get back under the bar? What's the procedure? Thank you

Deadlift: 345 3x5

Why so much deadlift volume? Unless 345 is light for you something was bound to give with all that volume.
