Stage picks the products. Athena runs a hard Grow→Bloom switch (never both at once) and swaps Core→Fade for the last 2 weeks — so A-parts and B-parts are pick-one.

mS/cm
Uses the tank size, target EC & products above. Tells you what to add to raise EC — or how much water to dilute if you're over.
Foliar spray
Separate spray tank — IPM, Stack foliar, Cleanse foliar. Never goes in the fertigation reservoir.

Root zone
Compare runoff against Athena's substrate EC targets, get the feed EC and feed pH that move the root zone back into range, and track runoff EC over time to time the next EC increase.
