hi sleepless, u picked a great strain there to start with. Amnesia haze is my second favorite smoke after "willie nelson", they are both very similar. it has a really amazing sweet head buzz with no lethargy or couch lock.
looking at your picture i would advise flowering her straight away for a few reasons. 12 weeks is a very long flowering time and she will strech into a long gangly sativa anyway. she may also be a challenge for a first timer and u might lose a week or two. then u have to dry and cure.
my 1st willie nelson grow went on for 24 weeks and i was well experienced with many grows under my belt.
my latest batch of willie nelsons are a week from finish now and damn it was a long wait.
