Healthy looking roots & little plants. I wouldn't mist the leaves at this point, thinking that to encourage roots to grow into soil, the soil should be moist. There is so much left in the leaves - they are still plump.

Would flipping the parent leaf over so the roots are on the bottom help? The leaves will reach for the sun and will quickly right themselves. Rather than mist the roots, I would mist the SOIL below the plantlets, so to encourage the roots to reach down for the water. Not so much that it's soaked, but enough to stay damp for a few hours.

I am not sure about flipping them...most I do is sprinkle little gritty mix to partially cover the roots, or smaller grit to anchor them, but otherwise let them grow - less they are 'bothered' - better they grow.

These were all sitting on top of the mix, and roots grew into it:

Yeah, if there are roots growing with the same proliferation out of the bottom, there shouldn't be much reason to worry. I just see two leaves in particular where the plantlet seems to be on the bottom and the roots on the top. Sometimes with my sedum burrito leaves, the roots tend to grow up instead of down into the soil. I rotate the parent leaf a little, and it tends to solve the problem. This case will probably work itself out on its own eventually.

If I can paraphrase Rina: " less they are 'bothered' - better they grow."

This really is very true in growing succulents, many of us have experienced it. Think for a minute where ever they grow naturally, where ever they drop & fall that's it, they'll root their way to what they need w/out anyone there to right them. I wouldn't water the mix or the soil, pls. be reminded the fat fleshy leaves are fat & fleshy w/water ALREADY, they don't need more, they can live off their existing moisture; it's counterintuitive I know, but they can, look at their plumpness, esp. Rina's 2nd to last pic. To water on or near the roots is an invitation to rot IMO.

Some kind of Kalanchoe leaf that fell to the side of my other plants among my Crassulacae. I found it & basically forgot about it, proving it didn't need any help from me.

Though I did change its pot once I saw how well it was doing to give it a sunnier spot w/ this other propagation, a Sans leaf.

Cheryl, those youngsters look great, yes, I could see sprinkling some mix over them, but nothing else. Rest easy, they really are fine, they just need more time.
