Couple things you can try...

Close your plug gap a bit more... .018-.020 maybe

Compression / leakdown test that cyl- see if it’s close to the others

Knock sensors - you can try running the desensitized setting to see if that cleans up timing on all- this is NOT a recommendation, but if u want to try it, you can- it’s up to you if you want to.
