Thanks for the compliment, I am not sure that I fit that grand a title of "guru" though.Only thing I could suggest different is start under the CMH or MH then transition to the HPS. I think it might have to do with the spectrums. But the reality is that I totally a newb in lighting.
Maybe @Nunyabiz can offer some insight? He's guru level in my books on lighting.
But my guess is the reason for that lack of stretch is a bit too much defoliation right at that critical point.
The plant is spending its energy replacing leaves vs growing up.
You could test that theory on your next grow by only very lightly defoliating one plant and see if it stretches while the others don't
