Yeah it's most probably the led light and camera that do the weird shades of green. As I can see in the last pictures, having something white in the shot makes it easier to judge colours. Or just switch leds off when you take pictures. They are not good for your eyes anyway.
Plants look good! Good luck with the grow.
I am having the same questions about sexing - by the time they show they will have been LSTed and ready for the lower scrog, and if they show balls, that place in the tent will be empty. Maybe veg only fems, or have spares in case. Any fems that don't make it to the tent, maybe take a clone and put her outside somewhere to fend for herself.
Thanks
I also have this small Wedding Cake (fem). She really needs a repotting
