Two things, when I bought 24 Hamilton DE 14k and 20k bulbs, I was told Hamilton would have new stock in March. Well, that came and went and I still don't see new stock.
Second, when I was running MH only, 14k, my Acro colors were not good at all. Their health was excellent, but no color and certainly no blue color. I added the LEDs and everything colored up nicely.
I don't think this had anything to do with spectrum, but the light intensity. When I added a lot of LEDs and higher par, they colored up nicely. So just keep that in mind as you go along.
