Would clear pics helpFor a growing plant your NPK should be around 500-700. That's just for Nitrogen, Phosphorus, and Potassium excluding all the other elements magnesium, iron, etc.. Including all other elements + your NPK, IMO your ppm should be 1200 - 1500 for week 3.
That bottom leaf with yellow spotting seems not enough calcium to me. There's nothing you can do to save that leaf but just make sure you add calcium to your nute since you're doing soil-less grow.
You mentioned nute burn. I dont see sign of it. How did you figured it out that you have nute burn? I'm more thinking that you dont have enough nute there.
But I could be wrong, hopefully somebody more experience can help you out.

Don't see sign of it either. We'll your ph is not that bad (should be 5.5) and I'm assuming here that you're feeding them regularly. Don't see sign of toxicity but IMO a deficiency. Take one plant and feed it separately with higher ppm (I'm assuming here that you're familiar with your nute) and see what happen. That's what I would do if those are my plants since nobody else want to chime in.
