Flowering Nutes

what would be the best nute for high yield's in bio-bizz light mix soil
heard that bio bizz bloom is just a base food during flowering which i have looking a nute to go with this what would be the best for me to get, doesn't have to be organic just something that will be very good at increasing yeild's

Any idea's

potassium is the key man. saltpetre (KNO3) has a NPK of 13-0-44 witch is amazing all you need to add to that is micro nutrients (PHos) i like to use fish blood and bone mix for it workes well

I've used the bio bizz grow, bloom and topmax previously although that was with the all mix - I think for the light mix you use the same but include the 'Alg-A-Mic' as well.

I also use a single dose of the Canna PK13/14 about 2 weeks prior to harvest which has helped with my yields too.
