Thank everybody!
I water my orchids once a week, most of them have been repoted from Sphagnum moss to a bark mix. the ones that still on S. moss get water every time the moss feels dry.
I don't mist my Phals' but I actually did for first time while fetilizing last week.
I've been fertilizing every week using as recomended on the packet.
And I don't know if those white spot are a fungal issue. the plant had mites recently but seems like is ok now. the top couple of leaves are brand new and growing, so... I don't know!
Question: ¿should I trim the roots and use the same pot or use a bigger pot?
I got my bark mix soaking right now to repot tomorrow.
thanks!
