The big spots is from leaves being wet and light on. Light is magnified by water causing light bleaching spots. You are showing magnesium and calcium deficiency as well. I would investigate your soil ph. I don't think your plant needs more nitrogen then your feeding. Green level is good. She might want more potassium and phosphorus though. If you want to spray do it at lights off so they have time to dry. It will also raise humidity and attract mold and mildew if running over 70 percent rh.

Great diagnose Roberts! Yes this seems to be the problem. I’m 1 week into the switch and understand that potassium and phosphorus are really needed at this stage. I’m using coco a and b but what other products do you recommended to get the required potassium and phosphorus levels. Is it too early to be using PK booster at 1 week of flower.
