What I notice from the pic is the lack of expected serrations on the leaf.
Looks like a re-veg.
This might account for the premature seed ejection.
Are they light dep?
These plants were
indeed re-vegged. My plants were planted in
August of '16 and survived all winter in a metal locker-grow set-up in the storage space under my deck with nothing but some insulation and LEDs. Wall slabs of those rubble puzzle pieces that you see in home and commercials gyms were cut roughly with garden shears and lined the interior and top cavity of the locker....
and two LEDs summing to be around 165 watts ended up producing enough heat to keep them alive. They were started on a 24 hour light cycle (just easier) and progressively turned down to around 18/7 light cycle, after which then I started a 12/12 light cycle [in Massachusetts - in January.] Not too long after, it starting getting much colder, and I was concerned that during the times when my lights weren't on...my plants were going to freeze. I changed the light schedule back to on 24/7 and had them vegging until April when I moved to a new place and were able to move them indoors. June first was when I kicked it back to 12/12.
Right now they're getting 10 hours of light and 14 hours of darkness.
