Yes, that does seem to make sense, now that you mention it. The Nitrates 
would encourage lush GREEN growth for photosynthesis, and the red, at 
least to some extent, is a lack of green. I think that is what I heard 
about tree leaves turning orange and red in the fall. Is that right?

Also, would any particular colour spectrums help in encouraging reds? I 
was wondering in particular about adding more blue light, like an actinic.

In any case, I will certainly try lowering the nitrates and watch the 
effect.
