Hi the seedling is 2 weeks old big devil autofem grown outdoors and at night brought indoors for a few hours of CFL lighting to supplement the 12hours of sunlight it gets. The leaves are yellow and tipping down as you can see...
I have many variables I dont know the pH of the soil or water, i dont use fertilizers yet and i have no idea what brand my soil is, i am experiencing slow growth too, however recently its gotten alot better. Please reply, thanks !
edit: rofl i forgot to post my pics :( i did now tho !

From my basic knowledge it looks like the edge of nute burn, nitrogen toxicity to be exact. But im no expert. Looks like a similar issue I had. But its doing the claw and showing signs of a hot soil

Looks like it may be overwatered. That soil looks like it's really compacted. You need a good aerated soil with some perlite. Could be the soil is holding moisture and the plant can't breathe. If that's the problem it can be fixed by transplanting into a lighter soil with some perlite.

Does overwatering cause yellow leaves? I have not fed anything yet !
The soil is retaining moisture but i dont water very often and it is not compacted, i can stick my finger in it with ease !

So where did you get the dirt you really need to know what's in it like I'll use sunshine mix 4 with light feedings of 300 ppm for the first two weeks that's for seedlings then the they'll go into the fox farm's ocean forest you can't use just any old dirt every dirt is different as for my analysis of your plants I would feed maybe 400 ppms of grow nutes you gotta have ppm and ph meter too ~ :lol:
