hey raptor, congrats on an awesome grow. It's just some strains rippen up differently than others, for some the amber color is really faint beige, for others it's properly reddish brown, this can last a while. you can actually just straight up harvest it now, some of those trychomes and all the pistils turn during the cure anyway. I did that for a gorilla glue auto and i got strong weed out of it , so you're good ! hope this helps ! 🚀
