chasv77answered grow question 5 years ago Assuming you are in proper distance from the canopy with your specific light, and have good temps, it may be just genetics.
I have a Chemdawg, notorious for being a "stretcher", and it never took off in flower
You should start to defoliate underneath the canopy for proper ventilation during the ripening of your buds.
Only take the leaves that are in darkness, or cant be tucked away from some of your underneath buds.
You may have to sacrifice some spindly branches as well, when/if she develops into a taller plant
Good growing for the rest of flower duration, plant looks good.
