Strange color on interior buds

Hey mate its not the easiest thing to make a remote diagnosis but I have 2 things in mind. This could be just some light stress, if your plant was too sensitive for the 24 hrs light. My second guess is that your ladies started building mold from the inside. This is typically happening if you don't have a proper ventilation/air flow in your tent. If the smell of the lighter parts is completely different and unlike the rest of the "healthy" buds, you should probably not smoke them! Mold is no joke.
