Slacker boob/increasing supply

FTM here! I am almost 4 weeks pp and exclusively pumping. A few days ago my right boob had a clogged milk duct and once I finally worked the clog out, that boob turned into my slacker boob. It is only producing about 1-1.5 oz each time I pump 😩 Afterwards it still feels decently full but does not hurt whatsoever. I pump every 2-3 hours (4 hours at night) and do one power pump per day. I drink water after each pump, drink body armor, eat lactation bites with brewers yeast, flax and oats. I also started taking sunflower lecithin to help prevent clogged ducts and improve milk flow. Does anyone have any advice for increasing supply on my slacker boob?
