Yellow new growth can be ilght stress or a micronutrient deficiency like Iron. To me looks like the plant is light stressed. I would dim or distance the light. Don't change feed and change light so you can learn which it is. Give a few days to see a difference between adjustments and take notes.

I think your plant looks fine. Your plant is growing faster than the chlorophyl can mature and fill the leaves as was said above. If it keeps getting lighter than it could possibly be a nute def but to me it look perfect. Also just for peace of mind you could always add some calmag, its hard to use too much of that.

That makes sense too, cause when I move some of my genetics from 25% 680w LEDs (18/6) to 100% 720w LEDs (12/12) the plants will looked similar on the new growth until they adjusted to the more intense growth.
