Brown spots need texture and location checks. Dry window-facing spots, soft spreading lesions, and pest speckling point to different next steps.
For phalaenopsis orchid, adjust the diagnosis around this plant profile: Phalaenopsis orchids need airy roots and careful watering. Yellow leaves, limp leaves, and root rot are often tied to old bark, standing water, or roots hidden inside an opaque pot.
Check whether spots are dry and tan, soft and spreading, or tiny and speckled.
Notice whether damage is strongest on the window-facing side.
Inspect undersides and new growth for residue, dots, or webbing.
Look through the pot for green, silver, brown, or mushy roots.
Check whether water is trapped in the crown or decorative sleeve.
Move out of harsh direct sun if damage lines up with the window.
Isolate the plant if pest signs appear.
Avoid cutting every spotted leaf until the cause is stable.
