Squat has been fine for me. Here's me at 325:

As for my current stall, should I deload and work back up with your prescribed rep scheme? I'm currently trying to make 2.5 lb jumps on my press. However, I think those are over. Another thing that I neglected to mention is my chin/pull up volume. I do sets with 2-3 min rests until I can't make anymore reps. Could this lead to overtraining somehow?
As for the deadlifts stall, they seem to come so suddenly. The first rep of the workset just doesn't budge at all. I'll definitely give it a try though
