If you post pics. You will get more help
I tried to view your pic. But phone won't pull it up

well would be nice to know how late into flower you are but im assuming you are at 50 or 60 days they look awesome to me everyting happening is suppose to fans will yellow off as the plant enters its last stages of life its using all available nitrogen to fatten up the buds hence why those leave yellow and fall of just let them be they are fine in my opinion and fyi you can post pictures on this site much more help from community if you did that.
