Phal. Sogo Vivien care/Introduction

[DragonSpirit1185]

hey everyone I am Brandon.
I have had some orchids before but have never had any luck with them.
Me and my ex went rather crazy and started this orchid craze.
So we went to a nursery called Peach State Orchids and spent like $100 on orchids lol.
None of them are alive today.
I fertilized them and went by several care guides but none of them made it.

here are some pics of orchids I use to have(sorry but idk all the species names):







this one here smelled soooo good:


I wish I still had some of them but they just bloomed then died slowly.

OK well here is the Phal. sogo vivien in question...




I just want to know what to do to make sure this orchid has a long healthy life.
I used Better-Gro fertilizers on my last orchids at the right times and when they were flowering I used Better-Gro Bloom Booster.
I used Better-Gro Orchid mix that had charcoal, perlite, and fir bark.
They would be ok then aver the spike died I would clip it and they would be ok then slowly start to die...idk what I did wrong but I wanna try to be successful with this little one.
As you can tell it is very small. It is a clay pot with a smaller plastic pot inside. The substrate in the pot is long fiber sphagnum.

I appreciate the help, Thanks
