I've never used rockwool, I wouldn't suggest it for clones although it is acceptable to use it as a medium. If the rockwool you got did not come pre-treated you need to soak the rockwool in pH balanced water for 12 hours or so IIRC, otherwise the pH of the medium will be unsuitable for growth. I've used peat pellets with a lot of success but I've recently switched to root riot pellets because I don't have to hydrate and I don't have to worry about over hydrating either. A little pricey at 25 bucks a bag, but you get a fuck ton of them so unless you make massive clone runs they'll last for a while
Since the picture you show is displaying wilted clones it means you do not have enough humidity in your dome, roots have not formed yet, and the plants are transpiring more water then they are taking in. You may want to consider wetting down some perlite and lining the bottom of your cloning tray with it, this will provide more than enough humidity for your clones to prosper and root.
Second bit of advice I can give you is fuck the timeline, never ever follow a timeline to the T because a.) every plant is different b.) too many variables are involved to give exact times when you should do this and that. Pay attention to your plants, that's what's important here.
Even though this is not a foolproof method what I usually end up doing is letting the clones sit for 4-5 days cover closed completely. Then at the end of that I will open the vents to release the humidity and get some airflow in their, if the clones wilt (usually happens pretty quickly if they're not rooted enough) I close the vents and give 2-3 more days. Also when I reach this point I will give a very gentle tug on the stems to check if they've rooted into the cubes. This gives me a good indication of how far they've come along, if they seem like they're going to pull out of the cube I know I need to keep that vent closed a little while longer. If they seem stuck solid I know I have a decent set of root nubs and I can start lowering the humidity. I try to wait until I see roots coming through the sides of the cube, but if I'm reaching the two week mark and they seem like they're rooted, I'll plant the clones and remove them from the humidity dome. If the root system is too tiny and the plant begins to wilt I drop the plant into a gallon ziplock and seal it for another day, and keep checking every day to see if it can support itself.
Another thing to point out is you need to keep a check on root zone temps, your plants will root faster if you can keep the rootzone at around 80 F with a seedling mat, but at the same time you want to try and keep the air temps in the mid 70's. Usually in the summer the ambient temps of my veg cab is more than enough to do this, come the fall and winter I need to use the seedling mat other wise the cubes get ice cold.
Cloning is about patience, and practice, and patience. The beauty of cloning is that you can practice as much as you want, I routinely throw away shopping bags full of cuttings that I don't need from my moms. A good bonsai mother can produce 20-40 good clones a month (rough estimate here), so theoretically you could do a small clone run every couple of weeks until you get it down. Keep in mind that some strains are horribly difficult to clone, while others root with no effort. I've had fully rooted clones take nine days, and I've had clone runs last up to almost a whole month before rooting. So just keep at it and you'll find what works for you, because (as I like to say) the easiest and best method is the one that works for you.
Good luck!

You have absolutely no idea what you're talking about, do you?
