Derrick's unknown orchid (Dendrobium or Cattleya, not Phalaenopsis) produces new shoots that yellow and die while immature. Two original shoots remain healthy. He fertilizes weekly with 25-10-10 in coconut husk.
Stop 25-10-10 immediately. It's high-nitrogen, promoting only vegetative growth, not flowering or maturation. Switch to balanced orchid fertilizer (equal or near-equal NPK numbers).
Identify by roots, then write back for type-specific care. Balanced nutrition should sustain new growth to maturity.
