Maybe you trimmed too much? I did something similar, back when I first thought it was a great idea to "let light in", trimming most of my upper fan leaves, at about week 5 of flowering. It stalled them in their tracks, and pretty much ruined the yield. Yeah, still got me stoned, but yield was cut in half.
