If your soil is slightly alkaline, you can also use this phosphate fertilizer solution to try, note: not calcium magnesium phosphate fertilizer, but calcium superphosphate.
The usage is to stir the calcium superphosphate into a solution according to 1RV 100 with water and let it sit for one night. the next day, take the clear liquid from the upper layer to water the orchid, and pour it slowly along the basin wall so as not to touch the new seedlings and buds. Calcium superphosphate can not only acidify the soil, but also supplement the phosphate fertilizer of orchids and promote the development of flower buds.
