The Myeonggwanggae Mystery: The Return of Yellowing Leaves

Remember that most orchids are VERY light feeders. You won't hurt them by giving too little fertilizer, maybe just slow them down a bit. (If there is a serious deficiency due to lack of minerals in the water, it can take months or even a year to show up) But you CAN harm them with too much. If fertilizing more often, then the strength must be reduced.
