Although it's not impossible, I rather doubt that your shrivelled roots are
from over-feeding. If it's only a few, then as Rob suggests, it's most
likely just "old age." If it's a lot of them, then you need to re-visit
your watering practices, and maybe take a look at the mix they're in. Some
mixes [particularly sphagnum, which is used extensively on phals] become
water-repellent if they get too dry.

Superthrive is good to stimulate new root growth but must be used with
caution. For a plant that is seriously depleted of roots, a one-time soak
[about 20 minutes] in a 10 drops/gallon of water solution will either do the
trick, repeating or increasing dosage won't help. Dynagrow's K-L-N is
another alternative. Good growing,

Hello Everyone,
Some of my phals have recently showed some signs of root shriveling, a
few are in bloom.
I think I over fertilized because the humidity is around 75 percent in
my growing room
I used half the strenght of the suggested dose and flushed them before
I fertilize, but still, root shrivel.
It's only a few roots luckily, but I want to keep them in good health.
A few are in spike, I was just wondering if it would be okay to cut off
the spikes to direct energy to root and leaf growth.
The plants look healthy, but I don't want to risk them using too much
energy on the buds and flowers.
As well, can anyone recomend some sort of product that will help
initiate root growth, and a more gentile fertilizer?
