I know this post is a bit late but I do not think these plants were ready to harvest either. the pistols turn orange three times accually. They will turn on NL #1 so instances on around 51 days then a new growth will happen and 75% of the second turning will happen around day 64. then at day 73ish a new third small growth will emerge. No extra wieght really but she will be tastie. The high is not as energetic but she tastes so good. I would not have any yellow leaves at harvest but I use 100ppm of added ions which is all you need. Dont add over 200ppm. Directions sell product and do not grow plants in every situation. Burnt tips are the first indication of over fertilizing. Then the leaves curl then they die. Better late then never I guess
One love
