Whats wrong with my seedlings?

[420AsianNigro]

Can some one tell whats wrong with this seedlings?
It's pineapple express auto, in week 1
leaves looks kind of yellow curly.
im feeding them with quarter doze of Fox farm nutrient and cal-mag ppm 330, tap water ppm130 ,ph around 5.8-6
temp is always around 75 and humidity around 70
so everything looks good to me
I have 6 pineapple express auto seedlings, all their leaves look quite yellow and light green mostyly
it is just this strain looks like this?
or anything I may had did wrong?

And the one is an auto strain i dont know the name
it's now in week 2, looks not growing any bigger at all, but the root is growing
it also looks a bit yellow as u can see.

Are you growing in coco? The medium looks saturated and it definitely needs more perlite - I like a 70/30 coco/perlite mix - more oxygen to the roots equals fast growth. Did you pre charge your coco?

I know the no nutrient theory in seedling while others claim that a little bit of nutrient is fine.
So since all other strains and even my other pineapple auto is doing fine but just this two
i dont think its a nutrient problem
does it look like light burn a bit?

 

[420AsianNigro]

nutrient burn it's usually leave gets yellow in the side, right?
but now the leaves are yellow in the middle and green in the side

I did washed my coco clean and let them sit in ph and cal-mag water over night
So i should just add more perlite?

Let them dry a little before you feed again and when you're ready to transplant, mix your coco with more perlite.
