URGENTSeedlings failing quickly on Ocean Forest, same conditions, different symptoms?

These are my exact specs:
https://www.rollitup.org/grow-journals/534840-closet-closet-400w-4-x.html

Cut to the chase, 400w dimmable cool tube in 4 x 2 x 5 tent
Not that important.

Fishy details:
10 plants
FFOF with 20% perlite
2 gallon pots
1 and a half weeks old
distilled water since day 1.

79 F - 85 F
40- 50% Humidity

Different strains are giving me different issues.
All plants are the same age, given same watering schedule (used to be every few days in peat pots, now once in the past 4 days since transplanting to 2 gallon pots) Soil is still VERY wet around roots, but dry on top.

Some have bad nute burn, on the other hand, some look like they have a N deficiency? But I doubt it.
It's the organic Ocean Forest, I know, but I want to know what my fellow gardeners think.

WHITE WIDOW x BIG BUD
AK48
BLUE MYSTIC
APHRODITE
GNOMO AUTOMATIC
NORTHERN LIGHTS

how old are they?

def not an N deficiency, they need very little at the stage they appear to be at. I personally have never had nute burn with seedlings in truly organic soil (obviously, not adding fertilizer until seedlings have nearly exhausted the soil's nutrients). I would guess a PH deficiency, have you checked into that?

Fox Farms has been known to burn seedlings..not a good medium to start them. Water when the individual seedlings need it not on a schedule.

Some of the tip burn.... Hmm is any water splashing on the plants while they are under that intense light?

Yeah I misted the tops but it's in a cool tube, so even with my hand 6 inches below the light, it's still pretty tolerable

My distilled was is at 7, of course, 002 PPM
I got a 20 dollar soil PH meter but no matter what I put it in, it always reads 7.... I have no idea why.
I don't see how the PH could have gotten off if I only use sterile, neutral water in high-grade soil
But I need to get a new PH meter.

Look at the 6th picture;
Yellow veins?
From my understanding, this could be a iron lockout due to incorrect PH.
What do you think?

Also, growth has almost come to a halt with the majority of them. They are all the same age, but you can see how much they differ.

I tested Ph, all pots vary between 6.1 to 6.7
Could this be affecting my plants so much?

Bumpity fucking reply

ocean forest is where seedlings go to die

use nutrient-free mix of coco or peat, perlite, and anything else you want that doesn't contain nutrients to start seedlings

that's nute burn on the tips

Well fuck! What do I do now?! I can't risk 'em dying, it would take another month just to order a new batch of seeds and get 'em going again!
Watering just activates the nutrients, how can I save them?
Maybe flushing all the nutes out?
I don't know man.

I'm gonna go get some dolomite lime today but that's not going to help the nute burn...
UGHHH

if you need to save them, i would slowly and carefully dig out the plant/s and replant them as best you can into new soil, doing as little damage to the roots as possible, and then water thoroughly with pure water

chances are the taproot hit the nutes and quit, so you won't have much to dig out and replant

Fucking damn, I wish I read up on FFOF.
I guess coco is a suggested medium?

anything without fertilizer or nutrients mixed into it...yes coco would work. Try to break as much of the current potting mix off as you can....gently, then give them a good flush. whatever you do, the sooner the better probably...get her done...good luck. update us

And then as soon as they start showing signs of hunger, I move em back to soil again? FUCK!
I thought I had everything straightened out then I can't even going 2 weeks without huge problems
