Nutes for bloom?

[OregonTentLife]

Ok here we go lol! I'm getting ready to flip in a couple weeks and need an effective nute for flowering. I'm kinda broke so.. I'm using ff grow big now with raw calmag, and I like to boost nitrogen too. I know general hydroponics is pretty cheap. Does it work?

The one I would recommend actually.
Use at 1/2 strength on the bottle.

The GH trio series works well for me.
