Lighting TOPled The Manual.

3"inches is fine with a CFL or fluorescent. an LED however, at that height can stop upward grow. When I first used mine, I had plants with node spacing of maybe 3/8 of an inch, I figure they were trying to not get closer to the light! I shoulda taken a pic, the plant was at the 5th node and 3 " high! Amazing the coping mechanisms they have.

That must be bleaching the tops. Mine were further away than that and the tips have turned white.

These two directly under the panels are showing a bit of bleaching but they've been close for weeks now so not too bad considering.
