Is this budrot on my first grow?

Hi guys, thought i would be just an silent reader in this sub. Got this far with low budget and some research. This is part of my first grow Nothern Lights Auto and after drying i'm checking the buds. It seems they have a more brown/yellow colour to the inside but im not sure if this is the begining of budrot or not. Research shows mostly still growing plants so its hard to compare for me. What do you think? Can i put it into a glas and if doesn't spread in the following weeks it's save? Thanks for any advice!
