Hey new grower, the hairs can be pink or even brown, these characteristics do not denote gender. That is determined by whether the plant displays these signs. Female plants generate buds then seeds as they mature and males, like us, have littlle dangling thingies down there. Or in their case all over there. My advice is to get extra florencent tubes, (I use four), then clone the plant into many cuttings and when they show vigorous growth turn the lights to 12 and 12 and they will all flower just as nature intended.

Hope this helps, good luck.
