Culture Lc Canhamiana v coerulea ‘Cobalt’

[NYCorchidman]

I had LC. Canhamiana "Azur Sky" AM/AOS.
It needs full sun and yes, it probably needs less hours of sun during the winter as it is a seasonal bloomer. Late spring to summer is the flowering season I think.

I'm not sure about the yellowing of leaves, does it happen to older leaves or new ones??
Does the whole leaf turn yellow quickly and then drop??
Does you plant grow normally? This plant should grow quite fast putting out at least two new leads a year. Do you see sheath on the mature growth?

Too much nitrogen causes leaves to get large, week, and deep green, while too little nitrogen can cause leaves to be yellowish and small.
