They're in great shape to super-crop, I usually start earlier but just make sure you give them a couple of weeks to heal & settle before they start flowering.
Some pointers:
Don't go too close to the tops, bend at least 2-3 nodes below
I squeeze them between my thumb and finger, use my thumb nail as a place to score them slowly, squeeze the branch against my thumb nail and use my finger to slowly bend it over my thumbnail. You can go back & forth until you feel it give way in the direction you want it, but don't fully break it. Depends on strain and how flexible it is, I adjust based on the flexibility of the branch.
To be effective you need to keep that bend at 90 degrees or slightly more. They'll try to bounce back after a few hours, tie them if necessary.
IME, there's no need for a break, a bend in the stem is good enough to get new growth (just tape it if it breaks too much for about a week, then you can remove it)
Depending on the success you should get new growth pop up within a week or so and will start shooting straight up from the area where the bend is (after 4-7 days you'll see a knot develop)
I marked some potential areas where you could SC, you can do one or all, depending on your comfort level. Bend in the direction of the bubble's shown and you should end up with some new shoots going up from the bends and turn into a ball. The top above the bends will stay there for a while, then eventually bend the top up towards the light. It's quite productive, I've done several strains and haven't had any issues. Some take longer to recover, some shoot out more than others. If you start earlier, like when they're 8-10", they're typically more flexible and easier to do.
