Printed out a retraction tower with the start retraction of 0 and an end retraction of 5mm (1st pic) and one going from 5mm to 7mm (2nd pic) with 0.1mm step. And as it's seen in the photo at no point the stringing seems to stop

I've tried this on different printing tempratures and yet the issue still remains. I used PLA on 190c for this one

what should I do to fix this problem? What setting should I change?
