as soon as those nanners open up and drop pollen , you will see a million seeds. or at least thats how my first one went. my 2nd hermie I manage to pluck all the nanners off and I dont see any seeds yet. so good luck. what Im doing now is instead of transplanting my plant, (cus now im pranoid about stressing my plant out) I take a rockwool cube or peatmoss starter plug. and I soak it over night in water and I put the seed in it, and I plant it in a 3gal pot. ... this way the seed, the plant, never moves its home. its start to finish in the same home. puts less stress on the plant. plants growing indoors are already under enough stress already, may as well minimize it... too much stress or light leaks of any kind can cause hermies.
good luck, hopefully its not a hermie.
