Phalaenopsis new leaves stress or pest?
All my Phals. new leaves are growing damaged near or at the crown.
My greenhouse has been hot and humid for several weeks. Around high 90's and at time above 70% humidity.
During winter these plants suffer a cold spell, thermometer indoors register 30 degrees but no damaged observed, nothing died.
My gut guess is that the plants are stress due to heat, combined with high humidity and dehydration. I have a hard time deciding when they need water when very hot and humid.
Please comment. Do I need to worry about pests or fungus?
