I know where to cut my losses, and since last night, I sprayed the seedlings with Super Thrive, and the yellowing is actually getting some green, so maybe I'll do one dose of that every 2 weeks.
Thank you Susanne, that is why I asked everyone to let me know if they wanted a private message. Also, since I'm still kinda new here, I had no idea there was a feedback forum...

My bad.
The only reason why I am not asking for the money back for the plants is because I really wanted some of them, and I think it's worth the chance to revive them. And anyways, they would have thrown them out if I sent them back... And even if 2 seedlings make it, they wouldn't have a chance back there.
