Hmm. Maybe we have a different version. Mine has six channels:The app is garbage, so bear with me here. I don't know what spectrum each color bar on the graph represents but here goes the max numbers: red 20%, gray 30%, burgundy 70%, blue 90%
White
Blue
Green
Purple
Light Blue (this is the almost UV one)
Red
It might be worth renting a par meter. These lights (if the same as mine) crank out a lot of par.
When I tested mine at 100% they were putting out almost 800par at about 4-6” below the water and something like 400+ at the base. It’s possible you’re overcooking them and stressing them out, especially with such a heavy blue weighting on the lights, when the lights come biased to blue already - there’s only a few red/green diodes so these will make up a small portion of the light output even when at equal percentage power as the whites/blues/UV(ish).
