Okay thanks for info really appreciate it.Happens. I had a few stay just the two round leaves and not bust a fan blade for 3 weeks and then explode into a plant that is too crowded/tight for light penetration. Then I've seen some never come at all. Then you got the crinkle leaves... As long as it keeps getting bigger, it will photosynthesize.
Yeah I am in FFOF so I am going to just keep an eye on it.Doesn’t look that weird. Your mix looks hot. I see a bit of nitrogen toxicity starting, maybe. Deep green leaves, and slight clawing. Bit if you are in something like FFOF this is normal.
I wouldn’t worry very much about it, just be aware that the beginnings are there.
Excess nitrogen also causes goofy seedlings. They usually grow with a lot of vigor though.
