Femanized plant flowering during long daylight hours

High, I just baught a sensiseeds femanized cbd #49 research pack of seeds. Its a hindu kush cbd x kush. I have never grown kush strain b4 and a short time ago i noticed it was dry, so i put it into a trug with water behind a large loganberry bush. I forgot about the fact it had been moved from a nice wide open space with full sun light to the new shaded area behind this bush.
I left it there and filled the trug with water every now and again with seaweed solution as feed and it started flowering, this is with 15 hrs of daylight.
Is this normal activity for a femanized plant or could something else be at work here?
Its in a 10ltr pot with ordinary compost and pearlite, some chicken manure pellets, seaweed meal and fish,bload n bone meal. it gets fed with seaweed solution when the leaves start to yellow up or i notice its rate of growth slows.
it has been through hell n back after twice being eaten by sheep, escaped from the farmers field next door, both times the plant had gone back in to full rigerous growth. So theres colas all over it rather then it being a single cola with lower side shoots.
the 3 pix were taken about 2 weeks ago and its much fuller now. ill take another pic when i clear my sd card out.

So is this normal behaviour for a femed plant or could it be the small size of pot im growing it in? any help much apreciated

stress or light beaming on it at night? half of mine flowered for no reason i slapped them under 15/9 of supplemental lighting and everything was back on track within a week or so. if you dont want to waste the entire season id do the same, other wise start a new one.
