I have a monstera deliciosa that I've had for about 5 years. Transplanted it earlier this year, and it seemed to do fine. I live in Seattle and winter is starting to set in (8 hours of indirect sunlight) and I've noticed the plants is starting to struggle. We're also fighting a small mealybug problem. So my question is - is the yellow speckling due to 1) root rot from moving it to a larger pot? 2) mealybugs or 3) not enough light. ANY advice would be great!
