I may be a bit late on this one. I lost almost all variegation (white on new and emerging leaves) after a few months of receiving my plant (from Satomi). This plant was labeled as a cutting from the original plant and so I suspected my culture over the genetics. I moved it to a much shadier part of my GH (near my Phals) and the leaves are now displaying the classing white characteristics. I doubt the roots will be as pink, I will probably have to fine tune the light (increasing it) to get both features.
I also moved a few more of my tigers into shadier conditions at that time and found that they also displayed more white markings.
Now I just need to find a place to keep my Hokage to get it to develop white markings again.
But have you achieved the inner variegation on the top surface of the leaf of the Houmeiden? White variegation on the underside of the folded leaf is easy. If it is a division from the original, any problem should not be genetic.
Your statement about other tigers is not consistent with my experience, perhaps we have different varieties of tigers. I have found them to require more light, not less.
