Hoyas should not be watered with mineral fertilizer solutions weekly. During the active growth period (March to September), it is recommended to fertilize the plant every 2-3 weeks, and in winter, reduce fertilizing to once a month or stop fertilizing altogether. Weekly watering with a fertilizer solution can lead to overdosing and root burn.
