4 Reasons Your Pothos Leaves Are Turning Yellow & What To Do
The pattern of your plant’s yellowing can hint at the type of mineral deficiency it has. For example, leaves that are yellowing at the edges but green in the middle could be low in magnesium. If a leaf’s veins and stems still look green but the rest of it has turned yellow, it could signal iron, zinc, or manganese deficiencies. If the leaves at the bottom of your plant are turning yellow, it points to a nitrogen deficiency, but if its top leaves are turning yellow, too little sulfur may be to blame.
On the other side of the coin, leaves that have mineral overload will usually appear scorched, with yellow and brown “burns” throughout.
