Welcome, and congratulations on taking the first steps in your journey to being stronger.
I can't say what's in the Second Edition book, as the Third Edition has been out for 12 years now. I understand that there were quite a few changes into this Third Edition that would make it worthwhile to pick up (and they've continued to make revisions). The reason I say that is that if what you're doing is outlined in the second edition, then it's definitely outdated and is sending you down the wrong path.
I say "wrong path" because your squat is 15lbs ahead of your deadlift when your deadlift should be somewhere around 50lbs or more greater than your squat. At no point during this program should the squats come close to matching your deadlift. For you, it's in part due to the fact that you started the power cleans right from the beginning, when the program doesn't introduce them until several weeks in. Up until that point, you're squatting and deadlifting every session and you continue that until you aren't quite able to recover from deadlifting that frequently; that's when you introduce the power cleans. See The Starting Strength Program.
Were you following the program correctly and making the same jumps that you have been, your 6/16/23 session would have had your squat at 135lbs (like you did) and your deadlift at 180lbs, which is right about where you need it to be. Even if you dropped back to +10lb jumps instead of the +15lb jumps, you'd still be right about where you need to be. And right about now would be the time to introduce Cleans.
You'll want to correct that sooner than later, as it will cause significant problems for you in the not too distant future.
But still, congratulations on taking theses first steps.
Keep at it!
