Cookies Surprise Clone

Another week down of flower and I am having a hard time with this clone. I gave her a good defoliation, which took forever and I didn't even get to the whole plant. I wish i put some more effort in making sure this clone was more clean. She is a giant bush and just keeps growing fan leaves and will need another defoliation during week 4 of flower. Something might be wrong with her, either a nitrogen or sulfur issue from what i have been reading. I increased the amount of grow big to see if the extra nitrogen will help but some of the older growth was definitely showing signs of something being wrong. I am trying to keep my focus on pushing this clone to the finish line but am having a hard time; wish i paid more attention when she wasnt such a monster plant lol. Hope everyones grow is going well! Happy Growing.
