To solve this we can use nitrogen based NPK fertilizer with leaf spraying. Another leaf yellowing and falling effect may happen due to higher water concentration of orchid roots. And chlorinated water directly damage orchid roots and generate whole yellow leaf. Sometimes this whole yellow can be seen due to the bacterial and virus effect. In this virus starting period, affected leaves should be removed and destroyed to prevent other leaves of orchid plant.
