Posting pictures taken in normal light is the only way to receive meaningful feedback.
Can't see hardly any details or colour differences under blurple lights, which you apparently know, but still used the pictures anyhow.
The pistils (hairs) changing colour as the plant ages is normal, but I can't see any colour change in the actual flowers.
You are growing Critical Purple, so I would be expecting some colouration changes in the flowers, but it is impossible to see in your pictures.
