Why is this turning yellow??

A ZZ plant's yellow leaves usually signal overwatering, leading to root rot, but can also mean underwatering, insufficient light, pests, or nutrient issues, with mushy stems and smelly soil pointing to excess water, while wrinkly stems suggest thirst, and yellowing on older leaves might just be natural aging or energy diversion for flowers. To fix it, check soil moisture, ensure good drainage, and adjust watering to only when the soil is completely dry, possibly moving to brighter, indirect light. Common Causes & Solutions
Overwatering (Most Common)
Signs: Yellowing leaves, mushy stems, black spots on stems, smelly soil, drooping.
Fix: Let soil dry completely between waterings (every few weeks); ensure pot has drainage; repot in fresh, dry soil if root rot is present, cutting off mushy roots.
Underwatering
Signs: Yellowing leaves, overall droopy appearance, wrinkly or shriveled stems.
Fix: Give the plant a thorough soak until water drains, then wait longer between waterings.
Insufficient Light
Signs: Yellowing leaves, especially if the plant is in a very dark corner.
Fix: Move to a spot with bright, indirect light (e.g., near an east or north window).
Pests
Signs: Yellowing leaflets, webbing (spider mites), white cottony spots (mealybugs).
Fix: Inspect closely and treat with insecticidal soap or neem oil.
Natural Aging/Flowering
Signs: Older, lower leaves yellow and fall off; sometimes happens when flowering (takes energy).
Fix: Trim off yellow leaves; fertilize lightly during growing season.
Quick Diagnostic Steps
Check Soil: Is it wet or bone dry? Water if dry, let it dry out if wet.
Inspect Roots: Gently remove from pot; look for dark, mushy, smelly roots (rot) or dry, brittle roots (underwatering).
Evaluate Light: Is it getting enough bright, indirect light?.

If it is an overwatering issue it is important to know that these are considered a succulent plant which means they benefit from being in a succulent soil. Watering about twice a month depending on the temperatures. Drainage is important. I found that a lot of plants tend to be watered officially when water is draining from the drainage holes at the bottom.
