Your soil looks very wet. How often do you water? Do the containers have drainage holes?

once every 8 days or so. im starting to think the cans had a effect as well as overwatering. I have 2 peace lillies in cans. And there damp and I havnt watered them in 2 and a half weeks.

There appears to be mould on the soil. Are there drainage holes?

btw straight sided containers are a pain when you want to remove your plants. There's a reason why the traditional flowerpot is conical.
