I'm about 9 weeks into flowering a sativa strain. I figured I would give them about another week or so to fully develop and plump up. I've noticed that new hairs are beginning to grow as if new buds are starting to form. Should new buds be forming this late into the flowering cycle or have I done something terribly wrong? I'm doing hydro with 600 watt lamps. and at this point it's just plain filtered water.
