On my big monstera the new stem is turning yellow and I'm not sure why. Are repotted it in June 2025 because it was rootbound it was pushing out a new leaf at the time. It is not pushed out a new leaf since. It got rust fungus I treated it with copper fungicide and chopped off the old leaves and still nothing. I checked the roots It was a tiny bit of root rot cut those off a month ago put more chunky soil in it as well It's been in the same spot. Same light. I was using Alaska fish fertilizer, and liquid earthworm castings. I ran out of both months and months ago so I just was using liqui- dirt. That was great. Now I got more fish fertilizer and liquid earthworm castings and mix it all together in my water mix Alaska fish fertilizer, liquid earthworm castings, and liqui -dirt same portions I've always used without a problem only this time when I watered it a few days ago the stem turned yellow 😬🤦🏾♀️. That has never happened before. Ariel roots are growing like crazy though. I'm at a loss here. Any suggestions?
