I'm in a similar situation with clones I took about six weeks ago. I cut down a dozen low branches from my girls and couldn't bear to just toss them so I put them in my clone machine. They all rooted. I moved them to Solo cups in coco. Two weeks later, they were getting rootbound so they went into one gallon fabric pots. BTW when you transfer them to a bigger pot, pack your soil around an empty Solo cup inside the new pot and pull the cup out leaving a nice cup-shaped hole for your rootbound clone to drop into after you work it out of its cup. After the transfer to fabric pots I topped all of them a week later to keep them from getting too tall. Magically, all those idle growth nodes along the stem woke up and started bushing the clones out a bit. You can still manifold if you have the short tomato cages (I saw some just yesterday at Home Despot). If it's your first grow, it might be a little better to keep it simple but if you have confidence go ahead and try it.
