nanners/hermies

ive got some plants that are at 9 wks of flower and are popping nanners
this is the same ak47 i grew from the same mother just 4 months ago. i went 11-12 wks on the last run but now at 9 wks i got nanners what could cause this to happen.

is not uncoomon to pop nanners late in flowering. if there are not alot, wet em and pluck em. if alot, harvest her if u r worried about others in the room. if not worried, pluck em till harvest-she prob wont have enough time to seed herself

thanks . i think ive narrowed it down to an earlier light leak or im wondering if its due to low temps during dark period
