My youngest are sick

Ok so this plant is 1 week old and im not sure whats happening to it. first the embyotic leaves turned yellowish, now the tip of the big leaf is starting to turn. A few days ago i gave them a tiny squirt of fertilizer this might have caused it.
i just wanna know if it was the fert or something else.

heres a better picture

First, stop with the ferts. I wouldn't worry too much about the seed leaves changing colors. If the real leaf changes more than just the tip then you should worry. For now watch and wait, maybe give it a flush.

no ferts yet...
but it looks like it will be fine dont stress it too much..

On one of my plants the little baby leaves are dead. I just am curious cause the plants arnt that big, and id rather stop this early if some thing is happening.

heres a better picture

any advice for me?

Those first 2 baby leaves are supposed to do that...they turn yellow and die. Your plants look fine!!

Yes webwalker is right- they are basically called cotelydons or something like that and they store the first little bit of nutrients the plants need to get going. so they will die off and that is completely normal. they look fine and healthy to me.

ha ok thats good to know, thanks for the help
