This looks like cement residue from grouting.
Also,Before sealing how long did you let the floor to air dry before applying sealer?
I would reccommend you use 600 grd sanding paper /wet process, to remove
cement stains.
then clean using a good PH Neutral cleaner.
Also feel that the joints are to big, with this type of floor joints should 1mm as not to disrupt the tile pattern.
