looking to clear up another convoluted issue (in my head) with the cotyledon and first true leaves...

someone questioned in another post if the "first leaves" always wither and die. there was no distinction in the answer if they were referring to the cotyledon or the first true leaves that wither and die. the cottle edens on all of my plants are dried and gone. now the first true leaves, the one fingers, are yellowing out and some are drying a little.

so, the question is do the first real leaves dry and fall off too?
