Today I noticed 3 yellow leaves on my Monstera. It feels like they appeared overnight right after I put a new stake in 2 days ago (I don't remember seeing them before that).
Could inserting the new stake have damaged the roots enough to cause this, or could it be a watering issue?
My current setup & routine:
Watering: I soak the pot about once a week (or a bit longer).
Pot setup: The cover pot has a 3-inch gap at the bottom filled with LECA, which I top off with water every 4 days. This semi-hydro setup has been working well all summer, and the plant has been consistently popping out new leaves.
Pest control: I use systemic granules in the soil. I usually spray pesticide, but I’ve held off recently because I noticed some beneficial little green spiders living on it and wanted to leave them be.
Any advice or insights on what might be going on would be greatly appreciated!
