Lights at 15 inches is too close for veg, 22 would be better. The others were correct about checking ph. Happy growing.

What is your run off ph? Is substrate ph in range. If chemical feed you need to wash old salts out as new go in. So a 20 person run off at minimum is ideal

Make sure you water with runoff and check that runoff pH/EC to determine it's fertility. To me it seems like pH related issue that shows in multiple deficiencies like Potassium (K) and Magnesium (Mg). Do not change feeding schedule and dosage unless deficiencies persist after pH has been balanced!! You should adjust your irrigation according to the runoff parameters to balance the pH to about 6.0-6.5. Hope this helps! Good luck and happy growing :)

Definitely looking like early signs of nute burn. I would just slightly back off the strength of your nutes and she should be just fine.
