Stripes like that are usually ph related, exactly why @OGIncognito is asking about your numbers. It favors calcium deficiency, but I’d put my money on root zone ph. And yes, 14 weeks in veg should see that plant 6 ft tall……

I agree. Once ya start seeing thoes rust spots, and the burns of the leaves begin turning greener than the rest of the leaf, it’s a good indicator of a mag deficiency. Be sure you have your pen calibrated, and it never hurts to have 2 pens. Once your oh is good in the RZ, the plant will begin to thrive again

Looks healthy to me. It looks like there was a leaf over top while it was growing not allowing it to breathe. Should be fine. Rest of the plant looks great.

The brown stripes on the leaves are a nutrient deficiency. Assuming the pH is correct, give them a good fertilize and make sure it has calcium and magnesium in.
