Should i stop using nitrogen (fish frets.)in flowering

Im doing an organic grow. I started the flowering cycle a few days ago and i was wondering if i should stop using the fish fertilizer or maybe use it very little, not sure what to do any advice out there?

Use less nitrogen and more phosphorous for flowering

You still want your plant to grow, but also to shift to flower production, so give her only 1/4-1/3 N compared to veg.
