Maybe think about switching squats to just twice a week. One front squat early/mid week in the week and back squats say on Friday or Saturday.
Doing a bit of exercise on off days, cardio, calesthenics, just bar drills with stick or bar might help recovery by getting blood througout the issues. The key thing is keeping it recovery and letting it turn into another workout.
Another mid 30's lifter and I were talking to a young guy in his young 20's and I remember how I was then. Invincible.
Now my warmups some days are slow compared to when I was 17 (half a lifetime ago) and literally just did our warmup run and hit the weights.
