Help on Blyxa japonica

[feide]

hi gurus

i just start this new tank, now day 6. Still cycling the tank.
The Blyxa Japonica(originally bright green) has started melting on day 2, now it is growing out leaves of light green with hue of redish gold, and some of the new leaves have slight 'tears and holes'
any bros experience this? i don't have good experience with this plant so paying extra attention.

So far the other plants doing quite alright, fingers crossed...
