Fe(CN)6]3- is a low-spin complex, whereas [Fe(NCS)6]3- is a high-spin complex. Iron is in +3 oxidation state in both the complexes. octahedral structure resulting from elongation along the z axis

Dear student 
High spin due to present of unpair electron and when there is no unpair electron in metal then it is low spin
According to Spectrochemical series CN is strong field ligand and it can pairing of electron But H2O is weak field ligand it can't pairing of electron
So [Fe(CN)6]-3 a low spin complex and [Fe(H2O)6]+3] a high spin complex
Good Luck
