Second vote to look at your gain staging.
I'll mix with everything on the master buss set up once I have a balance mix. There's a VU on my monitor chain and shoot for a touch over 0VU==15dBFS out of the gate (clipping when I start, -2-3dBFS at the end). I'll rarely change things after that, though I will check I'm making things better. Sometimes I'll change balance during the mix, so I have a VCA set up to control the volume on my main busses and can drive them up or down into the master if I need to. You could do the same with a trim before you master buss effects.
