Looks like you boards are a bit wide for glue-ups, that said here are few tips. (that you may already know)
How are you milling your lumber?
To mill your boards:
1. Cut to rough LxW (final size plus 1/4")
2. Joint one face
3. Plane other face (alternate faces till you get the correct thickness)
4. Joint one edge
5. Cut to the correct size at the table saw
How wide are your boards?
Your width should be 4-6" or smaller.
What is the moisture of your lumber?
8% would be great
