Nope , yours looks healthy
Yea ive been soak ing her alot, because of dry air here, had to buy a humidifier,
What ever you got going on, you definitely aren't in a bad spot. Are you adding nutrients? It's a common mistake to add nutrients too early when it's best to let them pull from their cotyledons for a minute.
with seedlings its better to have above 40% humidity ideally 50-60 to have them thrive properly.
Hmm personally i think that since you said you're using a compost that might be a little hot for the seedling then that might be it the seedling is gonna burn from any excess nutrients in the medium because it still has its cotyledons where its getting its essential vital nutrients.
also it doesnt look like that medium as any perlite in it which i would highly recommened getting a medium with lots of perlite
i would def look into getting some more basic potting soil and try to transplant into that
hope this helps
The Autos are autos because of the cannabis Ruderalis genetics involved, adding genetics from straight Indica (you didn't say if there were any Hybrid elements to your Afghan Kush) will reduce the amount of Ruderalis properties in the offspring. Keep us posted and try to keep track of differences between your purchased auto seeds and your propogated ones. good luck
