Help! Lots of problems with my babies! :(

Hello All, read a lot of threads and cannot pin point the issue. I have a 5x10 grow tent with two 450watt led lights (going 24/7), smart pots, and a fan. I have Botanicare ReadyGro Aeration medium as well as a three part Botanicare Kind nutrient system. I have 12 new baby clones (Sweet Island Sunk) and 1 larger veg (Sweet Island Skunk). I have a ph tester that was not too reliable but I have calibration solution to take care of it. When I transported the clones I soaked the medium with soil and left alone for six days (when the medium was dried up yet before they started drooping). I have the first round of nutes slightly higher then recommended and the ph was 6.5. The leaves are yellowing with brown spots and "burnt tips"; they are also folding upwards. I cannot figure out what I need to do next. Today I added some water with have the recommended nutes and also sprayed the leaves. The average temp is 78-84 and humidity is around 60%. Any advice?

Hard to tell with those pics. Would be nice if you could take some pics under white light then it will be easier to tell.

From first glimpse it looks like over feeding to me. Maybe dial back the nutes, most people use 1/4 or 1/2 what it says on the package.

I could tell you a hundred things. turn off the led turn on some white light . pics

Looks like overfeeding big time.
There's definitely lockout there.

Overfeeing?? Really??
Just to Shake things up:
In nitrogen od leaves go dark green and curl under in a claw like shape (see nitrogen claw in google).
To me, it looks like defiency, but them again im not am expert

Check potassium (burned tips) and nitrogen defiency (yellowing leaves).

I have also read that a powerful led, which you have, can also cause leaves goin pale if placed to close to light.

For me it looks like severe Iron deficiency. It's caused by overwatering , not enough drainage and to high pH.

Here are more pictures, I am not sure if I need to flush them or what the last thing I did to them was watered and sprayed the leaves with 1/2 recommended nut solution. I will not do anything until I get input from you pros. Do you think they are toast? I hope they are salvageable...
