The fact that the veg switch has more blue is what I'm telling you that you want to add to your plants if you can find a way!
The fact that either switch has more blue or more red means they have different spectrums bud. Adding more I both spectrums is awesome.
Having your lights at 6-7 inches is awesome. That is getting you tons of light.
If you could keep them that height or even raise them to 10-11 inches but use both switches I think you would be better off though because you would get more power and spectrum to boot.
