I never thought I would ask help for this..lol
Anyway, heres the problem. I had been growing some of my hybrid Phals outside this year due to space problem indoors. The plants are healthy, grow their spike on schedule, and then when the buds reach thumbnail size, they started dropping one by one. The buds are still firm when they drop, not yellowing or soft like the way they do when blasted. I didn't moved the plant either. First I thought maybe it caused by an insect? But the buds are undamaged, they just drop clean, still fresh. Maybe birds?
I appreciate any opinions.
