m0useanswered grow question 10 months ago I think your light is too close, but you should use a light meter to figure that out. or look at your lights manufacture specs and see the recommended hang heights and dim settings.

They recommend 100% at 12" but it might be to much. try backing it off to 15" or dimming it 10% if it allows that. My lights only dim in 20% increments.
