Lumpy vanda roots

[Michellekc1011]

Hi I was wondering if anyone has an idea what’s going on with my vanda. I thought maybe she was dehydrated but more humidity and longer watering isn’t helping. Right now I’m watering her once a day she has a humidifier and a little fan running. Not sure why her roots are like this. Anyone have an idea? I’m in New York and she’s indoors getting jacks 20-20-20 monthly also. Her leaves are good it’s just the lighting. I’d say it almost looks like a rubber band going up and down it.
