pistills turn orange when they get oxidized meaning rust which is where the color comes from. Basically the oxidization is when the outer memberane gets pierced or degrades for whatever reason (wind, light, age, etc) so it doesnt really indicate anything bad or anything good. What i can tell you is that your plant seems quite healthy and the buds will get bigger. it's totally normal to get worried at this stage, it looks like nothing is happening but if you check your weekly pictures you will notice the (slow) progress. Dont rush this part : it's an important part for the final harvest. Hope this helps ! 🚀
