I hope someone can help me figure out what's going on with this plant. I have what I think is a Peace Lily from my grandmother's funeral in 2018. It seemed to do well until around the end of 2021. In March of this year I determined from researching online that it had root rot (likely due to my scheduled watering instead of just when it needed to be watered).
I removed all plants and treated the roots with peroxide and water and removed the dead roots. I saw several videos on youtube mentioning this as a way to cure the plant before re potting. I re potted in new soil, but figured it would probably die. I cut all the stalks off down to the bottom and about a month later a tiny new stalk shot up. That was around the end of April. Slowly but surely it has been sprouting new stalks and making some small leaves. The tallest is about 4 inches now.
The problem I am seeing is that some leaves are starting to wilt and if you look at the tip of the stalk at dirt level, it's brown. I've seen several like that. I only water it now if it's dry about 2 inches below the surface and this seems to be working.
The plant spent its life in the corner of a kitchen with relatively low light. When I saw it start growing again, I decided to move it in front of a window during the day (about 4 feet away on a table). The window has blinds that are partially open and never gets direct sunlight. I really can't find a clear answer looking at information online, but I don't think the leaves could be "burning" from the location I have it.
A final observation is that I've seen tiny insects in the soil. I needed a jeweler's loupe to see them, they are that small. My guess would be aphids or spider mites. From what I've read, I don't think they could be the cause (I've never seen them on the plants or leaves). That's why I'm here though, I'm hoping an expert can help me get this plant healthy again. I'd hate for it to die. I've included several pictures that will hopefully help with a diagnosis. I did go out and buy a spray bottle of Bonide Neem oil from walmart. I saw a video where a woman soaked the soil in the pot to take care of an insect issue. After reading the bottle though, it mentioned to be careful around "tender" plants or new plants, so I was afraid to use it after reading that.
