How do i Improve my print quality?

I’ve been printing on my Ender 3 Pro for a while now, and I’ve pretty much been able to handle problems, but this one is giving me issues… I started having problems with my prints when I switched to a different filament, and thought I may have had a bad roll… I bought a new roll of filament, and was having more issues. The biggest issue is the seemingly partially completed layers. The benchy on the right in the photo was done at 200 Hot End temp, and the one on the left was at 210… obviously the left looks better, but I’m still having these problem areas as highlighted by the blue markings. I’ve changed my print nozzle and adjusted my print speed down to 50, but I’m still getting these weak layers… any advise on things to try is appreciated. Filament it Overture PLA from Amazon.
