There's a part that says :
"
To a lesser degree, when feeding a well-rooted plant, overfeeding can result in the production of vegetative growth instead of flowers, sometimes resulting in blind sheaths. In feeding, it is better to err on the side of too little than on the side of too much."
This might not be the case here though. But interesting details.
This orchid appears to be in good shape. Next bulb, and next time around - could bring a flower, and definitely share with us photos of the future bloom!
