Dont worry Catrina we always learn from the mistake and then it will help us. Original habitat of this C. Pandurata like in my country they are hanging very hard to the tree barks always very high from the ground. They are happy with the shadier place, light roughly about 50 to 70% with the humidity more than 70 to 80 %. When the condition matched than you can see the flowers emerge from the young shoot.
The leaf color is not normal by right should be light green and not yellow probably too much sun as you said. For your information C. Pandurata is very huge plant once they mature the bulb would be 3 X 5 inch. and begin to bloom. Please put your plant under the shade try to maintain the humidity as I mention above . Good luck. Catrina.
