Your leaf damage appears to be nutrient burn, I would slightly reduce your nutrient strength.

You want pH 5.8 for hydroponic and soiless (peat moss and coco coir) and pH 6.5 for soil.

Hey King John , dont forget about the PPM-nute strength. Always make sure your nutes arent to strong for your plant, other wise youll have nute burn as above :Namaste:
