The white LEDs are full spectrum, and have red/green in them already. At 3% the reds/greens make up less than .5% of overall light. Yes, they do have some marginal effect, but for the most part whether or not the reds/greens are on is a matter of personal preference. They're mostly for adjusting your lights visual color tone. Greens hit none of the photosynthetic peaks and reds do but only on a smaller mark. The importance of each color channel based on coral growth and coloration falls roughly in this order: Violets, Royal Blue, White, Cool Blue, Red, Green.
What lights were you running before, and at what percentage? That will also help me determine if the lights need adjustment.
Do keep in mind, these lights will change between set points, they don't change on the hour. So if you set the reds to 3% at 21:00, and 0% at 22:00, they will be off by 21:18 (1% every 6 minutes).
If you feel your light is not following that kind of schedule, you can certainly send it in for testing, but to avoid that inconvenience I can send you a Reef Nexus integration kit as a courtesy instead ($100 retail price- and not even released yet)- that will get you on the wireless app, which has more precise programming. Send me an email at logan at reefbreeders dot com.
I'll include a return label for your wifi chip so I can test and verify this. It sounds like the light is set quite low and simply shutting off early as those channels are at less than 10%, which is perfectly normal. But if you feel there is something off about your schedule I can install your old remote and wireless chip in a test light here and put it through its paces.
