Attention Growers: Week 4 And I'm Getting Ready To Cull

Of the 13 cannabis plants that I am current growing, 6 are presenting this way at the end of week 4:

I took this picture under 60 X magnification.  I "think" these are pollen sacs which indicate male plants.

This particular strain is Apollo 13  which was supposed to be an auto-flower. Of the 4 (Apollo 13 plants) that I have growing, 3 of them are presenting this way.

I have never grown an auto-flower before so I want to make sure that I am making the correct decision to "kill" these very healthy plants.

What do you guys think? Do You Think This Is A Male Plant? 

I welcome your comments. (I'm standing at the ready to be the Grim Reaper with a big-ass knife while listening to Blue Oyster Cult from 1976.)
