that whole plant is the size of one clone pretty much. so like 3-4 more weeks easy. besides a bigger plant has a better chance of surviving it. when you take clones, you want to take a branck that has at least 3 leaf set levels (your plant has 3) and cut off any leafs below those three. remember when taking clones never to take more than 30% of the mother plants leaves and branches, and try tu cut portions off evenly based on where you need more and less growth to get maximum light
