I have had my frag from Adam since December 2016. I'm only seeing shades of blue/green and red right now. No yellows. See photo. iPhone photo doesn't do it justice. Also, I just changed lights and moved it and flipped it on it's side. Seems to have lost a bit of color since all the changes. Had better color before the move. I also need to dial in the right spectrum & intensity on new lights. It seems like a moderately fast grower.
