.5-.5-.5 is a pretty low strength general plant feed. You generally want high nitrogen (the first number) for veg, low nitrogen and high phosphorus for begging of flower, and high phosphorus medium potassium for the end of flower.
My organics goes as follows:
11-1-1 bat guano
9-11-0 bone meal
0-11-2 bone meal
.5-12-.2 bat guano
I feed with the first bat guano and bone meal first. Bat guano is immediate release + slow release and bone meal is just slow release so my plants start with a little nitrogen which then ramps up before the phosphorus kicks in at the beginning of flower.
I then switch to the second bone meal and bat guano for the end of flower (I actually add this at the beginning of flower but it kicks in at the end as it is slow release).
