Phalaenopsis Orchid- Great leaves/ Poor Roots

[New2Orchids2020]

First of all-Happy New Year! 🥳🥳🥳

This is my Phalaenopsis Orchid. I've had it since September. It is growing a new leaf (see picture). Overall the plant is getting bigger. The roots do not look well. I trimmed the dried out roots when I replanted it November 1, 2020 so at that time all roots were plump....even if they may not have all been very green.

What is wrong with my roots? I only water when it is dry. I watch for roots to turn silvery. I water the roots and medium only never the leaves and I do not spritz with water. I keep the pot on top of a humidity bowl (small rocks and water) and the water level does not touch the pot.

I fertilize super weakly (1/4 of recommended amounts) each time I water (now extended to 2 weeks since I have the humidity bowls).
Fertilizer and Nutrients I use- Cal-Mag, Seaweed extract, epsom salt, Orchid plus fertilizer and garden lime (1/4 tsp on top of medium every once a month) All in a gallon of warm water. I water first in the sink in a large bowl and let them soak for 4 min. Then I drain all that out and pour 1/2 of the feeding mixture (1/2 gal) on the aerial roots and potting medium of each plant and drain out. I do not place the containers back on the humidity bowl until it appears that the roots are turning silvery again to prevent overwatering. Humidity is currently at 61% according to the gauge.

I unearthed it for the root pictures and when I did found one root that appears to be GROWING!

I need new roots. Please help.
