qbone, if you are still with us, i'll stick my 2 cents in
you might have gotten more responses posting it in the flowering section.
it is a little hard to tell with the HPS lighting on, but the buds seem to be forming OK to me.
it looks like you might have done some supercrop on a few branches, but you still have other branches up higher.
my advice would be to get some wires or string and get as many branches as you can get to an even canopy.
the plant looks a little lean and this would help optimize your yield a bit. get some of the smaller buds an even shot at the light.
I had a Sage n Sour that was a little sparse at 4 weeks, then all of a sudden it fattened up and surpassed all the other plants in the room. A little LSt and a little supercrop can really help a plant out.
