When was your last feeding and how often are you feeding? Watered 2 days ago
What size bulb are you using? 125 w cfl
What is the distance to the canopy? ca. 4 cm
What is your RH Factor? (Relative Humidity) hmm, like the same in the whole room I think
What is the canopy temperature? Just a bit over room temp.

So heres the pics, 2 different problems, but they have both come after I've transplantet into this soil..

The chronics leaves startet to curl up in the sides, and the deep chunk shows some kind of deffeciency or overfeeding..

hope you can read the soil back..

thanks,

overfed.
u need to get seedling soil mix without nutes and transplant into prenute soil after cotyldons die

pH could also be off since its not listed and the leafs look twisted, wrinkled like the pH could be off

Oh yeah.. Forgot that..

pH is 5-6, or thats what it says on the soil...

 

[Ziggaro]

that is also too low, you want it to be between 6 and 7, optimally around 6.6

The upturned edges is heat stress, raise the light a little.

The dying leaves is from incorrect ph as Zig said. Wrinkled twisted leaves are also incorrect ph. Zig is also right on about that soil being too hot for seedlings/small plants. It looks like a nice vegging/flowering mix, with the extra perlite.

The second photo shows me your plants are getting overwatered (dull green and droopy) because that soil retains too much water and doesn't drain well enough without extra perlite. You should transplant asap into a mix that has at least 30% perlite, or use coco which drains perfectly by itself.
