what are you growing in ? what kind of light do you have ? how far away is it ? what is your feeding/watering schedule ?what nutes do you use ? what is your PH ? how close to harvest are you?

Generaly this is normal and expected. It can be caused by other things tho. How bout a pic?

maxigrow bloom every 3rd water. water everyday when light comes on. 400hps 16in from tops. temp is 76 at that height. ph is same as its always been bout 6.5. in soil. super haze so im guessing im still a few weeks out from harvest. its about 90/10 sativa. some of the bottom guys hairs are getting mostly amber color.

one more question is can i harvestm the buds that mature faster than the colas. theyre still pretty white but a lot of the popcorn buds near the bottom are gettin mostly red.

what blunter said :thumbsup:---red pistils [hairs] do not indicate ripeness,they can change color for many different reasons .those lower buds will ripen LAST[if at all] not first.keep your eye on the calyx, when they swell turn a magnifying glass on the resin glands [trichs] and watch as they turn from clear to milky.when 90+% are milky your ready to harvest .some people will wait for amber colored trichs to harvest---with a sativa it could be a very long wait.with that said i should mention that i remove the lower branches and buds in order to focus flowering on the main cola.but i do it during the first 2-3 weeks.removing growth later into flowering may stress the plant and make it go hermi on you.
