I would run both 6700k lights that are good for plants and see how you like it. Give it a week or two and you might get used to it and notice more plant growth.
The blue / actinic lights look really nice, but I don't think they are as good for plants as the 6700k lights. I had one 6700k and one actinic light in my T5 HO
set up and I removed the actinic, replacing it with a second 6700k light. It looks more "ghoulish" without the blue actinic, but my plants grew like crazy. Of course, there were many other factors; i was running CO2
into the tank - which probably helped a great deal.
