They do look like hermies, and the way I see it is that if you are doubting something then there is good reason to doubt it. They are not what you are expecting to see. I just had the same issue with a few hermies, one plant starting showing male sacs all over the plant. It was removed due to having at least 10 male sacs very early on. One other plant had put out just the one male sac so I removed that 1 sac from the plant and it remains growing with no new male sacs or any visible nanners either.
I have a night vision camera in the room and I believed it was that so I unplugged it until I could determine which infra red leds it had inside it. After much research on infrared spectrums and plants and cctv I came to the conclusion that the camera could not be the issue as the worst plant was the furthest from the camera and the closest plant was over 3 feet from the leds on the camera.
I had never had any issues with herms ever in the past but I had to get this fixed as soon as possible as it was too early on to ignore. I convinced myself that due to the grow area being in complete darkness when everything is off that I had no issues with light leaks. I have 3 fans and 1 extension lead inside the grow area that has a red light on it that runs day and night. These fans lined up with the plants that had issues! How could I have missed that until now? The extension cable has a mild red light on it, I also that I missed too... I now have all lights covered and camera hooked up again and it has been a few weeks since the initial problem and all is good now.
So check for light leaks, go in just after lights off and look for leaks and lights on electric items. Also whats the temp change from day/night cycle? Anything over 10c change can sometimes be a problem.
