Flowering feed is for flowering plants.They are still stretching but there's enough nitrogen in the flower feed.They need the extra P and K to set the flower sites which isn't in the grow feed. Look at my 3wk old flowering plants and they've had even more PK from a bud igniter, and you can tell. If grow was best they'd tell you to use it 2wks in but they don't.

I haver heard some experts say half and half for 1wk.
