Every since transplant the leaves have been turning yellow. This is the plants on the First day:

The first day I over watered the plants, then I lowered the water level in order to dry out the pants.

After they dryed out I raised level and they continued to have yellow drooping leaves. I did a full flush for 3 days with pure dislilled water, becuase I thought I had nute burn/lockout.

After 3 days I added 50ppm nutrients which is about 15% strength of Dyna Gro's recommended formula for non-recirculation system in first week of grow.
The roots continued to grow but they leaves continued to shrivel and turn yellow. This is how they looked at about day 8:


Left that for 1 day then raised nutes to 50% strength.
This is how they look today after day 13:

​

Any help please these things look like they are dying.

I don't do dwc but it looks like your overwatering, your lights are too close for the stage your at, and you need to feed them more food. I don't know if your using tap or RO water to suggest anything on food.

Overwatering a DWC= Deep Water Culture... <<<----- You grow in water....
Is it possible?

After 13 days your root base should be a lot more established than it is already. Also you said your humidity is between 20-60 well 60 will be ok could really do with 65 70 while there still young but no way should it drop to 20. The pictures make it look as though they are under fed to me and very close to dying.
I would always do cuttings in a aeroponic propagator if i was to go into deep water culture just because rockwool stays wet for a long time and if your rockwool is soaked in the middle of those clay balls then you will have lazy roots
One of your pictures shows roots coming through now hopefully they will start to put work in and maybe your plant will make a recovery. I would suggest a good rootin hormone and somthing to help withnthe stress. I have a product called vita-link bio plus and its great for roots and stress plant, it is a bateria based benificial microbe but im not sure what products you use in US.

I'm a DWC vet and i have not had this happen at any point other than as they were developing roots in my cloner. Ounce they had roots off they went as normal. Not always but a few strains. Could be establishing a suitable root system for "SCURS". Self Contained Underwater Root System.

I used to grow outdoors as a teenager, grew DWC in college one year, about 15 years ago on a limited budget (not enough lights) low yield. I just started my first DWC with the right budget about 4 weeks ago.

So... take this with a grain of salt....

It doesn't look like they're dying necessarily. What it looks like to me is they got too much water and those bottom leaves felt the bulk of it and you caught it in time. I'm not sure if I would have flushed them. From what I've seen, nute burn makes the tip of the fingers of the leaves start to brown and move up the finger then they start to curl down (I once dumped a whole bag of red rooster on top of a 5 gallon bucket).

Your new growth looks fine, and they may just have got water logged from the transplant. I'd leave them on there. They could be a good indicator of a correction that is working. That new growth looks great though (on more than half of them).

Do you have a wick in the buckets pulling the water solution up, or are you at a certain water level over the bottom of the buckets?

are you positive the clones are all well established, ie: rooting?

perhaps i take bigger clones, but when you say 6inches, im thinking something i just cloned, and it hasnt really started growing yet. either way, how are the roots? you want 0 growth for the first week or 2 after cloning, and LOTS of root growth.

when my clones get stupid, i turn their lights off. that will push root growth and not leaf growth.

otherwise, once your sure they have roots, push some nutes and more light. let humidity start coming down.

What did you do for the plants? Did they make a recovery?

I'm having an issue with mine starting to shrivel. Roots protruding through roto rooter a air roots good suspended a few inches above the water don't know what to do. Using general hydroponics 3 part following feed schedule on light feeding schedule now using to water ph is 5.8 led only on half power suspended 36" spiderfarmer sf4000 growit hydroton humidity 50% temp 80. Deg.germination went well transfered to dwc when roots started coming through roto rooter. Could not make my own thread waiting in admin approval need help today hope someone sees this. These are all Autoflowers different strains
