Looks fine to me, buddy. Many plants will fade towards the end - some people complain that their plant isn't fading! She's just using up all the nutrients in those leaves and sending them to her buds.
Not sure where the first comment is seeing signs of pollination...? I'm seeing nothing of the sort in your photos. There's no male flowers on show and no pollen on the leaves, so it's quite a stretch to think it's been pollinated, particularly if that opinion is being based on the colour in those photos alone.
