Vanda - Brown roots and tips, hard water, sick, under watering or healthy ?

[Pabsorchid14]

Hi everyone, I’ve seen some brown spots on the roots of my Vanda. I have not checked if it has expanded but to seems the same as it was a few days ago. I have been using tap water that comes from a well, so no chemicals in that water, it has more calcium tho. I’m not sure if that’s the problem, as the root feels hard and plump it’s just the discoloration. I was also thinking it could be shriveling due to improper watering (Daily with atomizer probably 3 minutes until all roots are green and dripping). I would also like to point out I mentioned the water because I read somewhere that toxicity could turn the tips of the roots brown.

One more thing regarding the flowers, other than this Vanda the only orchids I e seen with flowers are phalaenopsis, so my question is do these flowers look affected by botrytis, bugs or something else or just mechanical damaged, maybe from rubbing against the metal wire or dehydration?

Settings - outside hanging from ceiling, plenty of air circulation and light, temp 22-32 C humidity around 50 , at night 15-19C. It gets plenty of light around 25-30k lux and also some direct sun for about an hour or so from 4:30-5:30 ish is this all right ?
