Angular 7 validation issue

Hi All wonder if someone can give me some guidance. I am using boostrap card html to display a list of information and some inputs/dropdowns using an ngFor loop. I am struggling to figure out how to do validation on each card. Today when my validation fires it validates all the cards. I have tried to move the form and ngfor to different sections of the code but all results I have tired lend me to the same result. I end up validating all cards not the card that the user is on.
