question on a plant

hi "someone" i know is growing some plants outdoors. Now the first set of leaves that sprouted only developed into three leaves , and not the five. Someone said that those "3 leafers" are no good and to pluck them off???
This is where i need the help....are they robbing precious nutrition from the "five" leaf leaves above.....or should i keep them there

Sorry for such a stupid question , but im kinda new

Thanks for yo help

 

Plants need leaves.
Never remove leaves.
Ever.
