Is this Zinc deficiency?

Zinc is an immobile element so it should not be showing on top of your plant.

you have that backwards.

mobile elements show up on lower leaves, nitrogren, phosphorous, potassium, magnesium
immobile elements show up on new growth, calcium, zinc, other micronutrients, ect.
 
I moved the LED away from the plant. She's doing better but whether it's because of the light or because what ever problem she had is corrected I don't know.

But thank you very much for all of your feedback. I really appreciate it :wink:
