It's best to take clones from healthy vegetating plants. That said, If I'm in a rush I'll take a clone that includes the third node of a young plant (leaving two nodes), then in a few weeks you can take more clones as the plant forms side shoots in response to being topped. Once they're rooted, be good to them. Give them at least a few weeks under lights if you can, and don't plant outside until after May 1st. Planting them outside before they're ready and while the ground is still cold only leads to frustration for you and the plants. Good luck, it would be great to hear how you turn out.
