Seedling problem pls help.

[william terrac]

Hi! This is my third grow but first coco coir grow in my 90x90 mammoth pro tent.
I got 3 x Quick one auto from royalqueenseed and 1 Northern lights auto also from royalqueenseed.
Lights:
1 mars hydro reflector 48 (150w)
1 mars hydro eco 60 (150w)
I am using bio nova cocobrix with 20% perlite in 4 19L smartpots.
Temperature is 24-28c° and humidity is 30-40%
The nutritions I use is GHE flora coco grow and bloom 0,5ml/2,5L
Biobizz root juice 2ml/2,5L
(I also got GHE diamond nectar, biobizz grow, bloom, alg-a-mic and topmax. But I don't know if they're needed for this grow.)
I am using my tap water with GHE ph down to ph 5,5 but I haven't checked my run off yet.

All seedlings looks healthy except one. One off them looks weak, pale and yellowish. I have no idea why this is and i hope someone here can help me.
Is it to much or to little nutes? Ph-problem? Root problem?
Please help me.

How old is that seedling?

A photo will assist greatly.

here is some picture. It looks like the stem is shrinking and it's about to die. It's only 5-6 days old.

Bro, it looks fine for that age.
I generally like to start auto seeds in 4x4 inch rockwool and transplant them into their final homes when the root tips hit the edges. Dontwater it until that topsoil gets dry.
PH your feed to 5.8.Other than that everything looks good.

I think you might lose that one. Start a fresh one.

How did you come to that conclusion?

Just gut instinct. Looks like a 1 day old seedling to me. His other 3 are better.

I wouldnt give up on that seed he thinks he has problems with. It looks fine. His top soil looks wet and if he lets it dry out the roots will go searching for water and thus it will grow and survive.
OP water around that little seedling. Dont water directly on the stem or at its base. Water about 1 1/2 inches away from the base of the stem when you do water.This helps push the roots to grow. Dont water the whole pot yet.
Putting a clear cup to keep humidity and vpd in check will help that plant through watever stress you think its going through. To me it looks totally fine. Ive had seeds look like that at day 7. So, youre alright. Use beneficial microbes, they help plants through stress as well. A good product is called recharge. Apply it next feed and it will be okay.
I dont know whay someone would suggest to give up so easily.
