Anyone familiar with what might be happening to my monstera adansonii? This is only on two leaves and they are towards the top of my giant plant. It’s near a south facing window and has been for seven months. It’s treated with systemic granules and there are no signs of spider mites/webbing. I spray it down every other watering with insecticidal soap as a preventative. I water when it’s almost 100% dry - I tend to underwater, and I’ve read this could be because of that. It’s been growing non-stop too! The first two pics show the two leaves that are acting up. The last two pics show a pic of the giant plant plus one of three new leaves it’s currently pushing out.
