There was no hormone.This one got only standard fertilizer in winter, 400 uS/ 2 weeks, npk was 1:2:2.Is this ‘Mt. Ito’? Looks big. That lead didn’t develop all the way, I’ve had a few Cattleyas do this, incomplete lead but pushes out a bud with no sheath. I wonder if it’s related to fert or hormones applied at some point.
