Just noticed some black crispy spots on several of my pothos leaves as well as two new growth leaves looking a little funky on the ends - almost chewed looking? This plant is hanging, so no pet access to it. Soil currently is on the dry side, plenty of access to sunlight, fertilized a month ago, TONS of new Growth recently, otherwise appears healthy and robust. No obvious visible pests. What gives?? This is the first plant I’ve kept alive and it’s been thriving for over a year. Photos attached.
