You have put the $ftp_site inside the ' thus protecting it from being
expanded by the outer shell, and the inner shell does not know about
it as it is not exported. Put it outside or 'export' it:

time parallel --eta  -j+0 'mkdir -p {2}/{1}; cd {2}/{1};  wget
ftp://'$ftp_site'/{1}/*.zip' ::: $(seq -w 001 004) ::: $(seq -w 11 11)

or

export ftp_site
time parallel --eta  -j+0 'mkdir -p {2}/{1}; cd {2}/{1};  wget
ftp://$ftp_site/{1}/*.zip' ::: $(seq -w 001 004) ::: $(seq -w 11 11)
