Time to chop??

No, unless you want a bad effect from your weed, or at very best not the desired effect. The longer you leave a plant it turns more indica. When did stigms start? (White hairs, pistons) usually after that starts it can take anywhere from 55-65 days for flowering. So go back thru pics and find out when she started showing stigma. My guess is she has about 10-15 days left, that's flush included and a 36-48 rest period in the dark. She is still showing higher than 30% clear, still too early pal.
