Tips on vanda can go like that if you disturb them a lot ( when they touch/ rub on something). To me it does not look like thrips.
Do you grow it without any media?
Do you see this thrips (pic below) on the roots?
That is thrip on phal leave i had last spring.
If you grow ut in bark you might have some other kind of insects. Once i saw something resembling thrips but it was springtail ( thank you to entomologist i have at work!).
On your second pic you have root with active growing tip, thats good.
