Paphiopedilum helenae - stained leaves, help needed!

[Robe]

Hello anyone.
I'm here to ask for your precious help.
Almost 2 months ago I bought a Paph. helenae because I was looking for a miniature hot growing Paphiopedilum.
I am not an expert Paphiopedilum grower but I particularly like this species.

Here's the Paphio when I bought it.
As you might have seen the current media is pure bark, quite coarse and the plant is quite immersed in the bark.
The plant is now on the bottom of my orchidarium, with LED lighting, ultrasonic humidifier and a fan.
Here's the orchidarium few months ago, now it's almost identical, with a few more plants in it (I bet you could have seen that coming )
Lately the temperatures reached 30 Celsius degrees (86 F) but never exceeded that.

This is the Paphio now. You can see some leaves growing but I don't really like the general appearance.


I suppose I need to repot it, check the roots and change some of its growing media and conditions.
Please, tell me what to do
