You're doing it wrong for starters... It also looks like you went into flower too soon. You dont feed the top back through down another hole, you pull the entire branch back through its own hole and move it outward. You are like weaving the plant thru the screen and thats not what you want to do. Anyways, once you get that sorted out, you typically pull 1-2 weeks into flower. I would do 1 personally.
