If you didn't change the rep scheme for squats before you moved to working out every three days, you messed up. Changing rep schemes maintains overall stress, but one-on-two-off actually reduces it. It basically just uses a minor deload or leaking effect to get MAYBE two weeks of progress out of the very end.
You can try 5x3 for squats. Squats tend to do better with topsets and backoffs. I would say go back to 3x a week with topsets and backoffs and a light squat day. Make biweekly increases until you can't, then you will be an intermediate. Read the grey book for how to do this.
Your deadlift is too light: I don't know if you need more volume, but you do need to increase it. For that matter, ALL of these are too light. You pulled volume too aggressively at some point.
