Brown hairs?

Is this normal all the other hairs on all the other buds on all the others plants are still white is there anything wrong with this bud like disease or anything humidity is good 50% temp is good and the light is not to close just cant figure it out.

they eventually will almost all be brown/reddish

its normal the pistils turn that amber brown color its a sign of maturation of your plant they will start to recede back into the bud your looking good pimp keep up the good work.
