You looked good up to week 6 until you started spraying your leaves. week 7 first sign of light burn upper leaves. Stop spraying your plants especially in bloom. never spray with the lights on. Try adding cal/mag into your nute regime week 4 with autos. Cal/mag issues start to show up by week 6 in autos. Cal/mag helps plants deal with stress of high intensity lights. I would try to simplify your nute/supplement line up you have a bit of everything. Low nitrogen med phosphorus high potassium for this stage of bloom. Nothing can be done to fix the leaves at this point.
