She looks good so far, there is absolutely no reason to remove any fans at this stage. Only when the plant is much larger and you are preparing for/in flower should you remove any fans, and even then only fans that block bud sites from direct light. Even then I would advocate tucking the fans under rather than removing them if possible.
Have you topped her yet? This would be the first form of trimming I would practice, and would do so when the 5th node has arrived (top above 3rd node imo).
