Drooping plants papery leaves.

Plants dying, looks like overwatering but it's not
Is there anyone out there that has seen or heard of anything like this?
So I'm not a noob and I've successfully grown plants in much harsher conditions than what I'm doing now, I've had them in all kinds of different methods with huge swings and fluctuations in different parameters and thought they would suffer even in 30c heat and below 10c cold, pH swings from 5-7 and I've never seen what I'm experiencing now.
So anyway this is the 4th time now that I can't make it to 12/12 due to this problem I'm having and cannot find why??
I'm using nft mainly as I've pulled some out and potted up in soil/coco mix to see if the problem still persist in which it does so that rules out the growing method.
My pH levels are good 5.8-5.9, ppms around 800, temps fluctuate between 18-25c, water temps around 18c.
Feeding with canna a+b as base nutrients with added h20, my roots all look good, nice white and healthy looking.
The problem I've got looks like overwatering problem but it's not.
Everything is pretty much perfect and no real reason my plants should be dying.
The veins in the leaves are dark almost like a purple hue to them before they start drooping over and start dying in which the leaves have this distinctive papery feel almost like what a banknote feels like, you can feel that the leaves have no moisture feeling to them like very dehydrated.
I thought I solved the issue by switching the led lights (2x Mars hydro ts 3000)
For a 400w mh hps light and they came back to life and started a vigorous growth and then boom they start drooping again and leaves begin to droop and go papery again.
As you can tell I'm very frustrated and I feel like a complete failure as I watch noob growers pot up seeds in their shed and don't even know what ph level means, they don't measure anything and pulling off 2 grams per watt.
Like seriously I have the most perfect setup, 2x 8 inch airforce silent ec fans, 2x Mars hydro ts 3000, I have airstones in my res, added supervit and h20, all my room and equipment gets cleaned with bleach thoroughly between cycles.
So yea I'm super frustrated!
Does anyone know if there's some kind of invisible disease or infection that can be doing this?
I've tried this with different strains with same results and even taken clones from the ones I have and they have done well in friends room, so it's not the strain.
I'm asking people around me what could be going on and they're just as puzzled as me!
I'm even beginning to think maybe my nutrients have poison in them or maybe my water supplier has put some extra additive in the water that could be poisoning my plants?
I'm really struck for ideas and I'm hoping someone here might of heard or seen anything like this before??
As I said I've bought them back to life once but it was only temporary.
I'd like to emphasise on the dark stems that you see in the pictures, this is the first sign that happens before they start drooping and feeling like paper.
I'll add some pictures so that you can see what mess I'm in.
Thanks in advance to anyone that even reads this.

Just from pictures and not reading what you wrote, looks like light stress to me. What indicates that to me is the way the leaves are cupping. Too intense perhaps if it can be toned down some. What size tent is that? I use a Mars Hydro tsw 2000 in a 3x3 and does well from seed to harvest

Plants look fine. Stop fiddling with it. Make sure it has good drainage, and your feeding it and letting the rockwool dry out.
First picture looks okay... looks stress, did you fiddle with it, like a transplant?
4th picture look like it getting light burn, getting tall to the light.

my clones look like the 1st picture, after a transplant. a week, and they shine back up healthy. you got air stone in your feeding tank?

I would try lowering light intensity way down and having 6-8 hour nights for a few days. Perhaps it will help. Perhaps it won't. Easy enough to try in veg anyway.

I've got half on an nft tray and half in pots now, it really does look like overwatering issues but it's not.
I'm thinking it could be some transpiration issues maybe.
I've got them under 2 hps lights now maybe that could help dry them out and bring them back
