Brown root tips in Laelia

[AnitadeWaard]

Hi, newbie here! I got a lovely little laelia orchid last week, it had happy healthy green roots that went over the pot but now the tips are turning brown. Room is 63 - 68 degree F, 55 - 65 % humidity, good light (E window + growlight). I have been watering with rainwater since bringing it home but I had to take it in my car/in a hotel for a few days so it might have been stressed by that, also I watered with bottled water en route so maybe too salty?
Should I repot it, flush with more rain/distilled water, or just leave it alone and send healing vibes??
