Clones wilting and can't figure out why!

[grassguy1]

Hey guys, first time grower and cloner here. I cloned my plants about 3 weeks ago and the roots became visible just over a week ago. I removed the humidifying dome after a week and they were kept on a heating mat which was removed recently. They're also under a 45w led.
I had a mildew situation last week and had to remove 2 of the clones, sprayed the rockwools with hydrogen peroxide for the rest and kept them near a light fan for a few days to prevent the mildew from spreading.
The mildew didn't show up but there was an underwatering situation 3-4 days ago and over half the clones have been wilting since then.
I water them with clonex nutrient solution(these days twice a day cause they've been getting dry more often.) and removed the fan to prevent extra loss of humidity but haven't seen any changes.

Any thoughts, ideas would be appreciated.

Pics help.

Here you go.

They look pretty much gone....

Yeah,those are gone.
Have you ever heard about rapid rooter cubes?
They are perfect for germination and cloning.
Much better then rockwool.
Where do you think the mildew could have come from?
You need to get control of that before you try cloning again.
Good luck.

Looks like they were way too wet and turned to moosh.

I agree they are goners looks like then wetness wicked the off you have to be really careful with rock wool it holds 20x it’s weight in water. You want them just moist. If you can shake them and water splashes it’s to wet. I switched from rock wool to rapid rooter plugs. So far so good. I’ve lost a number of seeds and cuttings from to wet of cubes. Also that’s where the mildew comes from wet and warm. = rot

That could be also.
I do think that he was using his nutes too strong as well.
Doesn't mildew occur when it's too moist in the room,the room never has a chance to dry out?

I love the rapid rooters.
I have gotten a huge success rate both in germination and cloning since I've been using them.

I’m 10 for 10 so far with them.
