The 2 ways that I am using now are, add more Potassium into the water & put more Yamato shrimp (but currently I have only 7 Yamato shrimps, still looking for more. Estimated 100litres tank need 40~50 of it to do the jobs.)
I think JBL & Tetra fertilizer has just a little Potassium inside, but the plant really needs more than that for photosynthesis.

Yes. I do read an article. Said adding Potassium - K2SO4 and increase the aeration will help to remove the BGA. It is faster than using the KNO3. I got 25KG of K2SO4 lying at home...
but please do remember, plants do assorb the nutrient/fertilizer when there is no photosynthesis. Lighting and CO2 is the main source for plants to assorb for running the photosynthesis. That's why you have to dose the Potassium when you are turning off the lighting of yr aquarium.
