I personally have done good with auto's, and with the joint doctor having the Easy Rider which can produce up to 2 ounces per plant...I think that's worth it. Growth I would email the doc like get high said, just to see what he says. Out of the 5 WD's I got, 3 out 5 cracked and all 3 were female. I doubt that they were straight males. It takes longer to show sex for females so the pistils may not have shown yet. Most feminized seeds are seeds from hermies, which means that if they're stressed they too will become hermies. They must have gotten stressed somehow. Did you ever get a new themometer to see what they canopy temp was instead of the room temp? Those leaves curling up and spreading like that means they are trying cool off, and if they were heat stressed that could have caused them to become hermies. Giving them nutes too early may have caused stress, but I would think that it's probably the heat. I remember your temps being about 80, which is just the room temp. I'd bet it's at least 10-15 degrees hotter than that under those lights.
