Serious help with clones

So I’ve got serious issues going on I can’t figure out. These clones were taken over a month ago from some monster plants. Cloned in rapid rooters. Rooted right away put in NFTG #4 and immeadiately they started suffering but only when under the light. I had issues with three plants that never took off for me from the ten seeds I started. I used them to try and figure out the light I bought. Want to clone and veg small I hope in a closer while I flower them in my grow box.
So here’s the details
Horticulture light group do it yourself 135 led qb
NFTG #4 soil
Small starter pots. About the size of solo cups
76 f
50 or so rh. Can’t get it higher they have expensive hardwood floors in there but mother plants did fine in those ranges but were grew under lec
Ph 6.2
They have never been fed. But the plants they came from went all the way thru veg and would burn if fed. All they wanted was whatever was preloaded in the dirt and water. Check out some of the pics of mine. This is all my first go. So I have a hard time believing they’re hungry but never know
18/6
Only getting about 200ml of water once they dry out. I had overwatering issues with the plants I took them from by overwatering twice and my strain likes to dry all the way out. Super light when I lift them. They love it for whatever reason.
But who knows. Maybe I am over watering.
Any ideas would be much appreciated. I’m not super concerned if they’ll live for about a month. Which I personally think they will. I hurt the mothers a couple times. Weed lol. But to me it’s something with the light. They responded well I thought when I dimmed it.
Lights 24 inches from them by the way

Perhaps too bright.

So dim it?

I think the plants are starving. You say the plants they came from went all the way through veg and would burn if fed? Was the mother plant growing in the same soil?

If you look at those they're going pale from the bottom to the top as the top takes the nitrogen from the older leaves. Nitrogen is a mobile nutrient and as the plant grow and needs nitrogen it will take it from the older growth to sustain the new growth to survive. I looked at that NTFG #4 and it doesn't have much in it. I'd start feeding those plants.

Ingredients: Sphagnum peat moss, perlite, coir fiber, pumice, mycorrhizal fungi, yucca meal, kelp meal, bone meal, diatomaceous earth, clay, basalt, oyster shell (for pH adjustment), humus and lime (for pH adjustment).

they look hungry....

Yes the mothers were started in the same soil.
