2 new ones with no care info!? Help!!?

[Awsorchids]

Hi all!
I'm new to posting here, and desperate for some advice... I just purchased Millenium Magic 'Witchcraft' (looks very healthy with two spikes) and bc. kosh Wallis 'Paradise' (also very healthy, about 6 flowers and a couple buds).

However, I can not find any care info, and the grower I bout from offered no info except that the Paradise could be kept with my Catts (outside, full am sun, then under patio from about noon. Nights reach about 55, days 65-70).

Can anyone help me with this? right now, I'm keeping then with my Phals and it seems to be going ok, however I have noticed that the leaves of the Withcraft are not as rigid or taut as they were upon purchase...?

Thank you!!
