Issues with new clones

Guys and gals I'm in need of ur help ...
I just get new clones in and stuck them in to my Aero veg unit ... I use cronk nutrients ...
I have 1000W led Philzon LED over them set on lowest setting ..
Clones came in rockwool cubes ...
I did previously start my seeds in Rooter plug and when seed sprout I jut put in Aero unit never had issues so I would assume Rocwool would be somewhat same ...
But those clones after few days show signs of stress .. leaves curling down and yellowing on outsides ... what would be solution .. any input appreciated...
Since is in rockwool I use timer 15 min on 30 min off for pump in reservoir

Too much light, too little humidity.

Agreed, far too much light.

Clones will root much better/faster if they don't get enough light for photosynthesis.
With the light you're giving them, they're trying to photosynthesize & since there's no roots they'll take nutrients from the leaves.
Your clones won't be inclined to put out roots if they can uptake nutrients from the cut stem.

So, IMO - indirect/ambient light & no food

Good luck
