What the heck are you growing those in, bark mulch? lol Either way, super hungry. Not sure if under feeding or major ph lockout, but I'm leaning towards option 2.

Have you tested runoff ph and ppm?

Is that the ph going in or coming out? Either way thats not great. And ppm? What are you feeding?
Pine bark is also very acidic and will throw the ph of the nutrient solution out of whack . You want ph going in between 6-6.5 and coming out the same.
