Monstera Adansonii. There's 2 on this one pole and they're both struggling.
Overall growth rate seems great, the leaves are growing bigger as it climbs, however the older leaves never turn opaque darker green, then soon develop these yellow brown spots on the edges, get crispy then full yellow wilty and die. The bottom "older" leaves are not even that old… they grew from the summer this year.
Distilled water with Fertilome All Purpose Houseplant 10-10-10 liquid fertilizer every time. It's the same fertilizer (and same water ratio) that I give my other monsteras and they never have this issue. I only water the moss pole and soil when they're dry but I don't let it stay dry for longer than a week for sure. I've been using the same liquid fertilizer for years. Admittedly I don't measure but the ratio fert:water, I just add a single splash to a gallon of water and use that for ALL of my plants… tropicals and my snake plant collection.
It gets indirect sun all day and direct sun for roughly 4hrs a day. Sits <2' from the window and right next to my monstera deliciosa.
There are ZERO pests! I can confidently confirm this as I am a thorough inspector. 🧐
Soil is my own aroid mix …cactus soil mix with added bark, charcoal, and chunky perlite.
Please help 🙏🏼
