how to care for Dgrma. Flying High 'Hawaii' ?

[pinkcatxx]

i recently bought an orchid, but the 'tag' that is shoved into the pot had fallen out and i didnt know what type of orchid it was or how to care for it... my mum just found the tag, and it is a Dgrma. Flying High 'Hawaii' orchid. But there's really no instructions on the tag/card/thing and i googled it, but still no good explanations, so how do i care for it?

(i've been watering it every 4 days or so, it's been going ok but its got some black spots on the leavse and this morning 2 of the 7 flowers on there have started to wilt.)
