the red hairs i wouldnt worry about either. my plants have red hairs on them as well which lead me to thinking that there was a problem or somethin but aside from the hairs, there have been no other signs of sickness which leads me to believe its in the genetics and some strains just have red hairs.
i would get a better pic but my babies are sleeping during 12/12 but if you want, ill get a good one for ya tomorrow. you can kinda see the red hairs closer to the end of the closest branch.
