It's auto blue amnesia right? Just making sure.. it looks like as if you got an iffy phenotype that still has some sativa or photo dominance to it. It's clearly still flowering, are the buds still filling out? Have any environmental or lighting changes occurred that could have stunted or slowed the bud development? I disagree with mclovin that the buds are filled out when you take into consideration the age of the plant. Especially with the level of light that appears to be hitting the thing. The plant looks more like it's 45-50 days old than 72. Might wind up running her 110+ days as long as she's still filling out.
Can we get a shot of it outside of the LED, in natural light?
