Peace lily does not require abundant light. It should not be placed under the air outlet or heating because it does not tolerate drafts well. So by removing the damaged leaves and placing the container in a suitable location without excessive light and air, we should see improvement.

Nutrient Deficiencies in Peace Lily – Yellow Spots on Leaves

Peace lilies are not a plant that requires a lot of fertilizer. However, yellow spots on peace lily may be due to a lack of nutrients.

The peace lily is susceptible to a lack of magnesium, but it is also affected by a lack of nitrogen, potassium, and iron. Nutrient deficiencies in plants can cause yellow spots on leaves, yellow leaves, and brown spots.

Why Have the Flowers of my Peace Lily Turned Green?

Why have the flowers of my Peace Lily turned green? This happens when the plant is in a place where it does not receive as much light.

The cause of the Peace Lily flowers turning green is that the plant is synthesizing more chlorophyll (the green pigment in charge of photosynthesis) in its petals, to try to maximize the rate of photosynthesis, taking advantage of the surface of the flower for this (which in conditions of higher light does not need it, so the flowers are white).

It does not cause any harm to the plant, but it may not be aesthetically pleasing, so I would recommend that you move it to a room or space where it receives more light (although without direct sun).

Lack of Flowering of Peace Lily

In most cases, ruling out that there is no lack of nutrients in the plant (we would see it in the visual symptoms), it is due to a lack of light.

Darkness negatively affects the growth of the plant and, in particular, the production of buds and flower buds. It is necessary to place the plant in a brighter location, but without direct sun.
