did you use hormone, also go cut the top of a 2L off and make a dome for each plant and mist 2-3 times a day and they should be fine. they look a little wilted, remember no roots means they have to take in watter in threw the leafs.
Mine looked way more haggard than that and they all rooted. Mist a lot.. Keep it humid.. I found one that I threw in the trast and it was growing and had roots. It seems like weed WANTS to root. To survive or sumpin,,
If you haven't seen anything in 10 days give them two weeks.. If you haven't seen anything in two weeks you may have a prob.. Thants how it goes for me.. Bigger cuttings will have bigger roots faster.. If you can't see any roots after a while maybe 'sacrafice' one and pull it out or cut the cube open and check the root growth.. Probably a better way to do this but that is what I do..
Also, I think your plants are struggling sending energy to too many places. You should trim most of the leaves off. That way energy goes to making roots, not leaves.
I have that clone with another not flowering, but doing great in Bubbleponic tanks, I have four more cuttings in organic soil. They are going well as well. Though I had one leaning like yours, I dug a pen in the dirt and tied it. Make it easy on her. LoL G.L.
