Serissa Flowers dying off
I was hoping someone could give me some advice on why my serissa is having flowering issues. The flowers die before they bloom, and the leaves around the blooms are yellow. The rest of the plant is greener than ever and growing at a ridiculous rate. I am watering the plant with superthrive and some liquid fertilizer. Temperature stays between 65 and 75, and humidity stays around 50%. I did recently spray this plant with a bug and mold prevention spray for indoor plants. I'm not sure if that could be causing it.
