Weez is right, Dutch. Yours are yellow. not white. And yours almost looks like heat damage, or spraying the leaves and lowering the lights, (steamed leaves) or stabbing the roots with a stake. (perhaps a bamboo one, lol). Did you at some point accidentally brush the plant against the hot bulb?

OP's photo's look like they never had chlorophyll to begin with.
Never seen light bleaching from UV light, but there was no mention of UV light anyway...
With a vented hood, (implying a glass barrier) a broken bulb envelope is ruled-out...
Only thing it leaves me with is genetics. Or...someone is dicking with us and doctored their leaves or washed-out the yellowing with photoshop. :wtf:
Can we get a good picture of the white while still on the plant?
