Chow_13answered grow question 3 years ago I would keep her, I have seen people pull some nice buds off some ugly plants. As long as you keep on top of removing any dead leaf matter you should not have issues introducing disease to your other plants. Check your PPM/EC runoff to see if you have over fed. If you don't have a pen its highly recommended to get a cheap one. They cost the same price as a seed and can help dramatically with feeding.
