NL Auto in early flower: Lower leaves showing signs of some type of deficiency and now all leaves drooping

Yeah, it is a crazy long list, isn’t it? I started with the liquid products from FF’s soil schedule, and then added in the Cal Mag Plus and some bud boosters. I am only feeding at half strength once per week, but the nute TDS is super high (I honestly don’t know the best way to manage feeding, watering, and TDS). Is it bad to give all nutrients at the same time using the same gallon of water? I add one nutrient at a time to a full gallon of distilled water, shake well, rinse, repeat. I have been adjusting the PH of both the nute solution and plain water (I have been using filtered water — maybe why I’m having calcium issues?) feedings. I do not water to runoff; however, some liquid makes its way to the bottom. I feed 1200 ml per plant when feeding nutrients and then give about the same in plain water when the plants air pots are easy to pick up. I imagine I am probably under watering. Is there any really good intro to managing feeding schedules and TDS levels?

Man you have a LONG list of nutrients. A lot of autos don't like a lot of nutrients. Aside from that are you waiting until the top inch of soil is dry before watering? Are you measuring runoff ph? If so what is it at?
