Yellow Leaves on Hoya Plants
My hoya plant has some yellow/brown tips. Is it due to over watering?
I think it has more to do with a fertilizer issue. I don’t know your feeding schedule but here’s what I’d recommend doing.
Spray the entire plant with a solution of one or two tablespoons of fish emulsion mixed with a gallon of warm water. Don’t drench the plant, just lightly mist it. Do this weekly for about a month, then go back to a regular feeding schedule. That would be fertilizing your hoya with a well balanced plant food diluted to 1/2 the recommended strength whenever it is actively producing new leaves.
