What’s going on red edges

26c is still only 78f
You need it to be 80s , like 82-85f

Your beasting them with light and they aren't warm enough to transpire enough to absorb the nutrients they need to match that light level.

There's not enough radiant heat so you have to raise air temperature.
I turned my led down to 50% was at 75 but it’s maintaining 55-60 th temp 26.c

Ive never seen pythium in cannabis except in pics so if it is so very unlucky bro i doubt it corey proly right your temps too low cos its led and u got a bit of deficiencies too

They look warm under that light with all those edges up lol. I still vote ec to high for a plant with no roots. Maybe a shitty meter and bad knowledge of ec and how to feed coco all together.

1.5.could be anywhere from 700 to 1100 don't you understand?
those are different scale measurements of ppm.. which one is used varies from country to country, U.S predominantly uses the 500 scale, and Europe uses the 700.. ec is actually the constant and the better reading to go by. (and 1.5 is ok)

Don't spray when the ligts are going to be on for an extended period, do it just before lights out. Also it's one Tablespoon per 5 liters (not teaspoon).

They aren't that young to not have roots and I agree with you in general, especially since they're in autopots which should be fed a lower EC than normal.

Thing is though is they aren't uptaking anything properly.
Two solutions, one seems to be to feed higher ec to make up for the fact they aren't drinking enough due to low transpiration.
The other is to increase transpiration.
I'd personally always go with option two when possible. But option one seems to be getting recommended more on here these days , though I personally think its a bandaid.

He was previously running lower temp with higher light intensity.
I might be wrong but I'd say they've been light stressed for ages and stunted overall.

There's two other things I'm not sure on.
One is his nutrients, can't see that been a problem though.
The other is his base water content.. so lock out.

I say no roots not cuz of age but because of health

Gladly say I could be biased and you could be totally right @ProPheT 216

Especially if they've had a bad start in them autopots, they're not exactly the best thing for encouraging a great root mass.

It's all part of the same triangle isn't it.

Not letting upload pic of roots so had to use other phone soz guys but I’m definitely thinking it’s the light or the magnesium also my stems are soild unbendable basically and I’ve turned my lights back down to 400w and currently at 27.c and 60rh but my plan was to go stay in 600w and flip next week and turn em on 720w I’m just tryna get em happy then flip
