fertilizing Q

Has anybody used botanicare series hydroplex bio-stimulant Bloom enhancer on outdoor plants?

0.5-4-10

and what do these number mean?

N-P-K thats what those numbers mean and no, I have not used that fertilizer.

.5% Nitrogen, 4% Phosphates, 10% Potassium, the other 85.5% is filler

Oh i see thanks for the replies bros. whats in the filler, water?

probably, there are usually trace minerals in there too if the fert company has any idea how to grow plants
