ive been using my w  f p for 2 weeks now , keeping checking water to see if any marks or spoting on glass , ive noticed slight spots on glass , my tds meter fitted to filtering unit shows 0000,  my hand held tds meter shows 0000 , the water pressure pushing water through filters is low at 45 psi , do i need a di vessel to do final polish of water , if so were the best place to buy one and how much

IF EVERYTHING = 0000 THEN NO

Yes,

If your getting spots then fit a di/demin. Even though your TDS meters read 0 they are not all that accurate.

Most systems are fitted with a DI already, and with you having a reading of 0 it seems like yours could have one.

The spotting will be coming from the soap left from previous cleans not the pure water.
