imo you're at a good stage for super-cropping. Just do it when you still have at least a couple of weeks of veg left so they have time to heal and develop new growth from the super-cropped areas. I use both FIM's and super-cropping to generate additional growth/colas. The area you super-crop will heal, then grow new shoots which have the potential to grow out new colas you wouldn't have had, they'll grow from around the knot created when you super crop so the bend you put in it should be cropped/bent in a manner to generate colas where light will get to them or you have/create open space. Just super-cropped a few branches after FIM's a week ago on some of these ladies, selected sites where I wanted new shoots to come up. Key is to give them time between whatever method you're using, super-cropping and FIM or Topping generate (high) stress to get hormones going and generate new growth, their considered high stress training so they should be given time to recover before flipping them to flower. I FIM vs. topping is it's less stress on the plant and generate about the same result, FIM recovers faster imo, lend itself well to additional methods like super-cropping.
