I'd say its fine to remove a few fan leaves in order to open up your plant more . Although its a bit early for that so I wouldn't go ham on that I would only remove the bare needed ones . You might also want to consider a way of training your ladies to open them up more maybe some LST or even you could top them and that would make the little tops shoot up . I would Start by removing the leaves that are touching the soil first this way it helps prevent any unwanted intruders to your plant as well as the plant well think its being grazed and will grow abit more in order to recover . Over all your well on your way to getting some kick ass medicine! I hope this information helps you to understand your options ! -Happy Growing!
