If your worried about them hitting the light, don't chop it. Bend it over, and done correctly it will not break..
one direction it will, you'll feel it. I start out pinching mine, when I know its done right, then start bending it
over at 90* angle, and use a string to tie it down or it will go back.. I've even broken mine doing this, she
built a knot at the break and did fine.
It very well could be the strain bro.. had same issue growing a friends Perth Poison from Australia, it just
did not like my humid environment and grew long dread locks, never went hermie.
Hermie issues can be caused be stress of any type, be it a light leak, high heat for the strain, over feeding, over watering.. all cause stress. sounds like you just have a strain that is very sensitive and used to a different
altitude, longitude etc.... switch your lights to 13hrs dark, 11hrs light... pluck any hermie nanners if you can.
this late in grow you won't get seeds, usually the popcorn white ones, still sucks..
better luck next run, if this a first... might not be you man...
