(respectfully offer a different reason): I've never seen any plant turn away from any type of light, not sure that's even possible, maybe a flower might, but not any vegetation....they dont need more light. They could be turning themselves away from the light because it is too intense. They dont even have leaves yet.
this is my thought, heck I place my lights even closer than that (I can post pics if need be) ...I'm wondering if those seeds were kinda planted too shallow...and from the looks of those plugs, too dry?More light, less water.
Move them closer to light and stop spraying them.
