Brown tips are usually repeated stress at the leaf edge. Brown spots can point to scorch, pests, root problems, edema, or physical damage.

Brown spots need texture and location checks. Dry window-facing spots, soft spreading lesions, and pest speckling point to different next steps.
For begonia, adjust the diagnosis around this plant profile: Begonias can crisp, spot, or drop leaves from uneven moisture, low humidity, direct sun, or mildew-prone wet foliage. Pattern and leaf texture matter.
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.
Check whether spots are dry and sun-facing or soft and spreading.
Avoid letting water sit on fuzzy or textured leaves.
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.
