I think you are misunderstanding what we mean by 'solar schedule'. It doesn't mean exposing the bird to sunlight, putting it near a window or taking it outside, it means not turning on any artificial lights where the bird is kept until the sun is out in the morning and turning them off when the sun is halfway down to the horizon in the afternoon -and keeping ALL lights off until the following morning when the sun is out. Your bird's cage seems to be in a human living area so, unless nobody uses this room at night and no light is coming in through the window (lamp on the street?) or from an opening to the rest of the house (light in another room?), she is been exposed to light when she should not. I have birds in my living and dining room but neither room is used when it turns dark (we just walk through them in silence and darkness

) and this is the reason why we eat our dinners in our rooms and why I don't have company in the winter unless it's for lunch. I even have a black-out curtain in the opening to the kitchen so the light in there doesn't reach the birds at night...
Also, on diet, giving them produce daily is great but you also need not to free-feed any source of high protein so, if what you are doing is putting high protein food (seeds, nuts, pellets, etc) in a bowl in the morning and leaving it there all day, the bird is eating too much protein.
It's not only not touching the tail, it's not touching the bird ANYWHERE except her head, neck and cheeks (just like you did on the video).
Also, her cage is waaaayyyyy too small (it's only good as a sleeping cage), she has only one dowel in it (real bad for her toes, feet and legs, you need to use tree branches) and virtually no 'chewing' toys or anything for her to climb (all you need is a nice tree branch tied to the side of her cage so she can climb up and sideways - and you can hang things for her to chew from the smaller branches that should grow out of the bigger branch you are tying, kind of like a tree trunk with branches growing out of it - just make sure the wood is not toxic and that it has been washed well and baked in the oven at 300 degrees for 20 minutes).
My Congo gray is now hormonal because this is the time of the year for it but she doesn't act that way because as I keep her at a strict solar schedule and do not free-feed high protein, she never gets overly hormonal.
