What soil you using? Looks like very hot soil.
I've spilt nutes in soil before when seed had just popped and thought nothing of it. One large cotyledon pointing up, one down dying, were the initial symptoms. Then was a very small mutant for about 25 days, I wish I had just got rid at the start.
Looks exactly the same as what happened to my fast buds six shooter.
Just giving you a heads up, you might be in for a slow ride here.
