3-5-5 sounds like a good organic fertilizer for flowering.
It gives some Nitrogen so the fans dont go yellow, but not too much. And it gives Phosphorous and Potassium in higher amounts for blooming.
The best way would be to top dress around the stem.
I doubt you can make a tea out of it because not all organic amendments will dissolve into the water. They are better in the soil.
Water with molasses spiked water. The sugars are very good for microbes which brake down the organics you used and the molasses has others things in it your plant can eat.
