As @vostok stated ... Grab a loupe or at least take a good close shot with your phone so you can zoom in.
Also ... Highly doubt they are harvest ready at week 4 ( 28 days ) ... That's less than a month flowering. You about halfway there ( week 8 ). Pistils ( hairs ) can and do change color for a number of reasons ..... The WORST ONE is that your plant got pollinated.
Kick back and run the course.
Pics would help or it didn't happen .... Playground rules.
