Question on tritium and patina

Hi Guys, so i kinda just pulled a trigger on a full set 14060 tritium. When I came home and put the watch under UV light. It seems like the hour / min hands tend to glow slightly greener tone compared to the hour markers and around an extra 20 seconds longer compared to the hour markers.

Am I thinking too much and over worrying? Seller mentioned that everything was original and no parts were replaced before.
