You have a middle stage manganese deficiency, potentially an early calcium deficiency as well. You do not have any magnesium deficiency. Please note the difference between manganese and magnesium. Do not use calmag.

Remedy this situation immediately by purchasing organic young coconut water from a grocer or health food store. Dilute it 50/50 with clean water (no chlorine or chloramine) and add 1 teaspoon of whole milk per 1gallon of solution. Spray this mixture on the tops and bottoms of the entire plant two or three times on the first day, with at least 4 hours between each spraying. You can spray this with lights on. Store in fridge, and add fresh water and shake before each use. Repeat a single application before lights-on each day until new growth is perfect green and glossy.

Foliar spraying will remedy the issue fastest. You can also add organic young coconut water to your waterings one a week until harvest to maintain manganese availability. Use the foliar spray each day during flip from veg to flower to increase bract development (bud density and biomass). Cease foliars once 3-5 pistils are visible at each flowering site.
