The hairs are the pistils. And watch you dont over water her. Theres a couple pics on here where she was over watered. And those meters dont work. They aren't calibrated right. And I seen where someone said to fluctuate your ph. No. Do not do that. In soil you want 6.00-7.00 I mean it will adjust some. Try to keep it 6.15-6.25 constant. Every watering and feed. Make sure you have good drainage in the bottom of that bucket. If you dont already drill a bunch of holes in the bottom. And it wont hurt to dril on the sides too. It will air prune the roots. And send new roots. Happy roots equals happy flowers.
