Can someone identify this problem?

I recently planted these in rockwool 2-3days ago. I suspect it's magnesium deficiency but from what I read magnesium deficiency shouldn't show symptoms until week 6

Check your roots should be healthy and white, if yellow back off the water a bit. Could be rotting rots

Ok thank you very much. Can the damage be reversed?

Go longer between watering, also when watering jus mist, until moist. Doesn’t need to be soaked. Do you have a dome to keep humidity up?

Well I soaked the rockwool cubes to lower the pH before I planted them that's why they are so wet.
No dome, the humidity in the room is at 60%.

Do you think this damage is reversible once the cubes dry a bit or should I just start new ones?

Pretty resilient little plants, their only desire is to live. Lesson learned and I’d say let them dry a bit and see how they do. No harm in letting them ride for a bit and see playing with the watering schedule, and amounts. Personally up to you, I only say this cause I just went through same ordeal and germ some behind so jus in case. So totally up to you

Ah thanks for the advice man. I've never encountered this problem before and this is new and valuable information.

As we learn we grow, usually your leaves are a direct reflection of your root system. Literally, and mistakes are meant to be applied! Happy Harvesting soon enough brother! Happened to me as well

Was that set of leaves left wet? The new set looks unaffected. Hard to tell exactly from the pics but it looks like mine if I mist them and leave big drops, the led bleaches them quick like a magnifying glass...

Like this maybe?

Hi
Yes I sprayed some water on them while the lights were on.

Yeah, the droplets act like little magnifying glasses. They'll be fine, just flick off any excess next time

Def want to wait to mist when lights are off. He is correct
