yellowing leaves?

my cotyledons are yellowing. once again, im still pretty new to this. idk if its jus the cotyledons dying n are about to fall off, or if theyre more sensitive leaves, n i could see this with my oother leaves or what??...

Your plant is fine. Cotyledons always turn yellow and eventualy fall off.

Somehow the first single blade leaves on my plant yellowed up and died but everything above em is perfect..i winder if a plant needs a boost early on if it would suck the life out of a lower leaf to get itself growing...because the yellow never moved up..
Sorry back to you...dont worry about the little rounded leafs all they do is pop open the seed their job is done

The cotyledons job is t just for seed opening. They also supply the new seedling with energy to start it's life and food while not getting nutes. It's very common for them to die off after the plant starts growing. If a perfect grow, they can actually stay alive and green right up to flowering. It's very rare but does happen. My latest plant kept them right up to two weeks into (roughly) of 12/12.

oh, cool. i figgered it was just natural, but jus thought i should make sure.

yep, they are just there to power the creation of roots and first true set of leafs. although they may stay on for a long time its not a big deal if they don't.
