Black Phalaenopsis Root Tips: Fungal Warning, Check Mix

Some root tips turned black. Why? Prevention/remedy?

Cause

Black tips = too wet → fungal infection. If not spreading, may reflect past wet conditions now contained. Prolonged damp + poor air exchange → root rot spreading along root.

Action

If spreading: unpot, check roots in mix, repot in more open mix.
Open mix = better air flow, less wetness.
