I'm learning the song "Waimanolo Blues" which is a Hawaiian slack key guitar song using a variation of open G tuning. I'm using a Harry's Guitar tutorial on YouTube and am struggling with how to play the verse and chorus. He plays the chords as finger style instead of strumming. I'm trying to figure out how to know which strings to pluck. I'm trying to slow the video down but just ain't seeing it. Can someone take a quick look at about 14:09 and explain? https://youtu.be/Wlb9FMMIy3w?si=jwTA9lyYKY0DDU1Y

I would really appreciate it!
