Light leaves on month old clones...light bleach? Reveg sideaffect? N deficiency?

I am trying to sleuth a problem with three of my plants. These three
plants are semi-established clones I acquired (~1 month old) of
Pineapple Kush. I acquired them and they were in an odd early
flowering state with some pistils showing ut no budding. They are
extremely bushy with incredibly close node spacing and such BUT almost
zero real fan leaves beyond singletons. They are completely covered
in single or at most double leaves.

I have these in my grow room under 400W of Vero29 LEDs @3500k.
Environment is pretty stable at ~45% humidity, temps ranging mid to
high 70's right now and good air exchange. Lights are currently 24"
above the leaves and being run 24 hours in an attempt to flip these
back into vegging.

None of my smaller seedlings that are a week old are showing any
problems whatsoever.

These clones, however, have just started some odd
lightening/yellowing. Initially it looked like a N deficiency but
these were all recently transplanted into 7 gallons of fresh FFOF so
I'd be very surprised if they are starved for nutrients.

My other gut reaction was that I just finished this grow room and
added all the reflection so the light levels these are getting went up
substantially about a week ago.

Right now im treating by a light dose (1/4 strenght) of veg nutes and raising/dimming lights for a bit until i diagnose this.

I have included some pictures below taken in natural light.

Questions:
1. Does this look like classic early N deficiency?
2. Does this look like initial light bleaching and I just need to
raise my lights and let the plants get used to the intensity levels?
3. Related to the single-bladed leaves on these clones and their
light flowering state, could this be related to the plants trying to
switch into vegetative mode? Will they drop these single bladed
leaves as they begin putting out proper multi-bladed fan leaves?

Looks over watered and revegged. It won't drop the single bladed leaves. Leave them on 24hrs and they'll start to grow regular leaves again, but it can take a couple weeks sometimes.

If you're not familiar with mobile vs immobile nutrients it can help narrow down what deficiency you have.

Deficiencies of mobile nutes will be seen at the bottom of the plant in the older growth first. Nitrogen will start yellowing bottom leaves and translocate it to the new growth to keep it green and healthy.

Immobile nutrient deficiencies will start at the top affecting new growth.

Those problems happened before the transplant right? 7 gallons of ffof has enough nutrients in the soil to feed that plant for a long time so adding the proper amounts of water is the only thing to do now and hope it recovers as far as adding anything to help the plant. Adding Nitrogen to fresh ffof is a big mistake. There is already a ton of nitrogen in fresh ffof. If you did not know that then you likely messed up in the other pot in some way by adding something it did not want. 7 gallons of ffof with a small plant like that is a water only soil for IDK at least 2 months.

If there ahould be zero chance of nutes not being available and i PH my water to 6.8, would that point to a cause unrelated to nutrients making the leaves start to yellow? Might it support the idea this is light bleaching of some kind?
