I posted something last week about my plant leaves yellowing with super soil and a GSC Extreme auto. Its getting way worse and not sure what to do as im 3 weeks into flower. I wanna get this right so my harvest is good because this plant trained and showed amazing signs of turning out great. I do not add any nutrients due to the soil being a super soil but im thinking im going to need to. Please help!
Soil- FFOF Organic soil mixed with an autoflower specific super soil. 1:4 ratio

EDIT: I watered tonight with 6.6 Ph water and this time i added cal/mag, i believe its either that or a nitrogen deficiency but idk.
