I concur with @Broken_Monitor's and @mipadaitu's recommendations, but I might add, don't overthink it, or wait to overthink it, anyway. I have been doing pourovers since before there was a YouTube circus about it; longer than Hoffmann has been publishing videos about it, anyway. In my early days I didn't have a scale (I did have a gooseneck kettle and a terrible, cheap grinder). I brewed everything pretty much the same, in a way that is now generally understood to be wrong by the way. It was always good coffee.
Go get some pointers from Hoffmann and Hedrick by all means, but the main thing is, score some good coffee and don't be overwhelmed.
