I'm curious. My daughter's an artist and a gardener. One of the first things she did when she got a tank from me was study the possibilities of the LED fixture, and adjust it. I became very jealous of her largely algae free tank with fantastic red plants growing fast with no ferts. She found the lighting that pleased the red plants didn't please java fern. That makes sense.
I grow Cypts like weeds with my factory settings (blue reduced, however). Her crypts did poorly, but she had my nemesis, stem plants, growing like greed. I'm leaning toward the idea of developing two different basic styles of tanks. One size fits all is baggy and dull.
She had to give up the tank due to a very recent move, and I have it here with her settings notes. I'm playing with the adjustable lights but adding root tabs as well. I'm using her notes for selected tanks. I wonder if anyone online has charts of what settings work with different plant species? Has anyone here found that?
