Discolored new floor (Vinyl Plank)

We had a downstairs bathroom floor fitted 9 months ago that is not looking good. It is cared for in exactly the same way as all of the other floor of the same type in the whole house. The rest of the house looks great but the bathroom does not. There are white discolored areas forming between some of the boards.
Floor is Paradigm long board supposed to be 100% waterproof and has a lifetime warranty in residential areas.

Does anyone know what could cause this?

Hard telling, could be detergent residue from cleaning. Looks like when it's cleaned, liquid can get into the cracks then when it dries, leaves a scale. Try cleaning it off with some goof off or paint thinner on a rag. Use a toothbrush if you have to... preferably not your own.

Vinyl is sensitive to anything with chlorine or bleach, so you might look at what cleaners are being used on it.

If directly on a concrete floor with no underlayment foam or fabric, it could be effluorescence from the concrete being carried by moisture.

Good point, I missed that "downstairs" could mean it's over concrete.

I wouldn't think so, effluorescence is the evaporation of water with salts that remain, if it is a concrete floor the evaporation would likely take place below the flooring, not on top.

I think the cleaning, or even water spillage, on the floor and evaporating leaving calcium deposits are most likely!

Try a mild solution of vinegar and water with a tooth brush on a small area, let it dry and see if that removes the white haze.

Thanks for the responses.
I tried the mild detergent and vinegar and it removed a little but not all of it.
It's on a concrete floor, as is the rest of the downstairs. It's all cleaned in exactly the same way but this one floor which we had fitted last year is the only one with issues.
The floor company that laid it say its coming from a leak under the flooring.
But he might mean its effluorescence. It does indeed look like salt crystals. I will try cleaning again.

Try licking it and see if it's salty. If it is it's efflorescense.
