i finally have them praying again, and the color is coming back. after lowering the light from 700w to 350w i've noticed some nice growth the past few days, they are starting to stretch out a bit. this was my first time vegging with this fixture, i think it was overkill even at 4-5 feet distance.
numbering starts at bottom right corner, always counting right to left from 1-10, so legend is
10, 9, 8
7, 6, 5
4, 3, 2, 1
2 is very compact still
4 is bushiest, new growth is nice and green
10 is starting to branch out, may be tallest
