Leaf edges turning yellow in hydroponics

I agree with the rest of the advice here but if the roots are turning green, they are healthy. To me, the leaves do look variegated which is a really nice bonus. Sometimes light or other circumstances can affect variation in plants. Those that grow Vanda falcata sometimes experience plain green leaves for this reason.
Good luck with your orchid. I hope that with the great advice you have been given by the others that this will thrive for you and gift you with some lovely flowers! If you have any other questions, please ask.
I decorate in green!

I have found, in general, that most orchids do well when getting a 75-125ppm N solution weekly, so when I "fertigate" them as often as you, I stick to 25 ppm N.
