Hi all! New Monstera leaf has a few black spots along the edge. None of the other leaves do. No signs of thrips or pests. The soil is Premium Monstera Mix from Rooting For You (usually exceptional quality), but it seems to retain moisture much longer than the Planta app expects - I'm only watering every two weeks as it takes that long to feel any dryness in the top inch or two. A couple weeks ago a couple small mushrooms sprouted up (a sign of over watering?). I figure it's a watering issue....any advice is much appreciated!
