That sucks man, there's always next time. I'm nowhere near a precise enough gardener to even attempt coco, too finicky, and autos are also not forgiving and finicky. I like good old fashioned dirt. Currently doing my first auto and I too am not having a fantastic first experience with them. One got stuck and I had to manually remove the casing, so it got stunted obviously, the other was looking great then dropped balls at 3 weeks and I just sent him to the great weed field in the sky on Saturday. Can't win em all. My runt is looking ok now though, yours could make a comeback.
