My set up. My challenges!

[Dri312]

Hi! I would like to share my set up with you guys to see if I'm going to the right direction. I'm a beginner that read all the pages of the sticker "the abuse of Phal ends here". My Phals are located near to an east facing window, with a ceiling fan 24/7 on medium velocity (around 10ft from plant stand). I placed a new humidifier (germ free humidification- cool moisture) that also has a fan inside to help with air circulation.
I'm using the wood stick method to check when it's ok to water them. Usually I'm watering every two to three days (soaking for an hour in distilled water). The larger pots takes longer to get dry so I'm watering according to the need. I used the Kelpmax once or twice (1tsp/ gal) and used 20-14-13 Orchid Plus very weakly on every soaking.
Temperature inside the house is around 78 with AC on. Humidity is never higher than 50, indoors (I live in Bakersfield, CA. Desert weather!) It only gets higher if I spray distilled water in the air, around the plants.
This is the set up:


This is my "old" Phal that I transplanted from semi-hydroponic to bark (orchid mix - fir bark, coarse perlite, charcoal and chunky peat) recently. I can see some new root growth but yesterday, it lost 2 of its lower leaves.



Most of these Phals (8 of them) are rescued from a generous manager of a hotel on May, 27. Some came in soaked wet vases. Some in better condition but, definitely, all of them in moss. I have one that I thought the sphag in bag method would help. I did according to Ray's website. I soaked first with Kelpmax and placed inside the ziplock bag with a damp paper towel without touching the plant. Here is the pic. I was wondering if I chose the right amount of light though... Maybe I should place in a darker area?!


I would like to have your opinion about how I placed my plants. So far, I'm a little disappointed because I expected more development. I'm anxious to see if I'm doing everything I possibly can to make them thrive. I believe my problem is the humidity. I would love to keep my plants indoors without the need to purchase a green house.

I'm still confused about using KelpMax and the fertilizer. I never used both together with the distilled water. Either I use one or the other. Am I doing it correctly?

Here are some more pictures


Also, do you think I made too many holes in the pots? In one of the plants, the wood stick came out moldy. I rechecked the roots and took out the dead ones. Repotted with new bark mix.

Sorry guys for all the information and pictures. I just would like some assurance that I'm doing the right thing.
Thank you so much for your time. Really appreciated!
