That doesn't mean you shouldn't correct the problem. It is a disease after all.as long as JUST the cotyledons die and fall off thats completely normal
the thing is its not a problem or a disease, its how the plant matures. as long as the rest of his seedling looks and acts healthy, it's fine. the cotyledons die off of all seedlings wen they dont need them anymore
THANK YOU NUGROWER2010!! i've tried to explain this but apparently someone thinks i'm jus a 'dumbass', and had to tell me this with a +rep so the coward could do it anonymously. then they wanna act like i'm not gonna kno who it is haha. dont kno shit about even SEEDLINGS, but i'm the dumbass. lmaoYes tupac is correct. The Cotyledon (small rounded leaves) serve a purpose when the plant hasn't developed it's "true" jagged leaves yet. This purpose is to help feed the plant until it can take care of itself. Once the jagged leaves sets grow, and the plant can produce it's own chlorophyll, the Cotyledon wither and die, thus falling off. This is completely normal and as long as your true leaves are still green and healthy-looking, your plant is perfectly normal.
(I know it's 2 yrs later...but still if anyone else wants to know) Well...if it just sprouted moments ago give it some time...it will become green as it soaks in some light.... Most probably urs is a hybrid plant.Hey guys, Duck here. Will you fine folks please educate me as to is it normal for my city's to be coming out of the soil looking yellow and kinda like a raw peanut?
