Huge noid phal: Is this phal. sogo yukidian?

[Autumn Child]

This is my newest purchase. A huge white noid phal that i think is phal. sogo yukidian.

The flower spike is over 1.2m tall with huge flowers measuring up to 14cm. Roots is growing like crazy. I have never seen so many roots growing at the same time, but there is diformities in the two new leave growths. The plant is also about to shoot new flower spike.

My question is the following:

1) Is this phal. sogo yukidian?

2) what cause the leave to deform? is this a disease or caused by other anomalies? the diformed parts feels harder than normal leaves and feel like scar tissue.

3) I am happy to see so many root growth, but is this normal while its flowering? or the grower added too much root hormone?

4) What should I do with the new flower spike? Do I let it grow or cut it to make the current spike last longer?

Thanks
