Hey Doc, some of my seedlings were super deformed, looked similar to the top pic. All but a couple lived and are doing very well. I read somewhere that mutants should be chucked, I sure am glad I didn't follow that thinking.
It depends on the type of mutation For instance if he had a tri-pod those are the type of mutations that ya pray for. But i've had weird looking seedlings grow into normal plants(although no mercy is probably the culprit here). Just like even some of us as children prolly looked a lil weird, but we all come around lol
