English Ivy Yellow Spots: Spider Mites or Overwatering

Ivy brought in September, potted, west exposure 8 ft from window (bright, no direct sun). Yellow leaves with brown/black spots; new growth present. Sprayed before bringing in. Expert Darlene:

• Check for spider mites: flashlight for webbing in leaf crotches.
• If found: spray 2 cups alcohol + 2 cups water + tsp dish/insecticidal soap every 3 days for 5 treatments (kills hatchlings).
• Alternative: overwatering. Ensure not constantly wet.
• Ivy survives winter outdoors unless far north.
