How to make my phalaenopsis orchid healthy again?

[zozoka_X]

Hello everyone,

I am a fairly new orchid owner I have had two phalaenopsis orchids (one white, one purple) for more than one year now.
One of my two orchids(white one)has done its blooming circle wonderfully, had full bloom in the last three months and is now growing very fast with new leaves spurting out and leaves and roots spurting out on the branch. This started happening more intensely when (after reading on it) I cut the branch that was completely dry and not supporting the plant anymore and actually I have left a part of it still in the plant not having completely removed it from the core of the plant just trimmed the top of the branch. I hope this makes sense.

So I am happy with one of them. The other one, bought at the same time I have been taking care of it in exactly the same manner as the other- I water them weekly just a tiny bit and include some orchid food in the water, just a bit again.

The second one has not bloomed since the first time it bloomed which was when I bought it. Its leaves started growing at some point and now have become again wrinkly and one of its leaves I decided to cut because it was completely dry and and yellow (maybe that was a mistake). However, I still have hope for this one as it has some new roots coming out of its core. I include pictures of the first one (one) and then the second one (two, one whole and one of its roots).
Any assessment advice on either one of them would be really appreciated as I do want to continue taking care of them
