Athena Feed Chart – Blended Line Doses and Fade
Athena's own published Blended Line schedule. Millilitres per US gallon and per 10 litres, week by week.
- All dosesper gallon / per 10 L
- pH5.8 – 6.2 in coco
- Base feed11–32ml of each part
Each cell is ml per US gallon / ml per 10 litres. Grow and Bloom are two-part — the figure is for each of A and B.
CaMg runs at 3–5ml per gallon (8–13ml per 10 litres) alongside Bloom. For the 700 scale, multiply the EC by 700 instead — Athena print both.
Getting it right
- PK, Balance and Fade are sold separately. They are not rows on this schedule, so no doses for them are given here — follow the directions on the bottle if you use them.
- Mixing order for this schedule: Grow B, Grow A, Bloom B, Bloom A, CaMg, Cleanse — each part fully dissolved before the next goes in.
- Cleanse goes in every single feed, at every stage. It keeps lines and emitters clean, which is why it never tapers.
- Pre-soak the medium. Coco at pH 5.5–5.8 and EC 3.5–4.0; rockwool at pH 5.0–5.5 and EC 2.5–3.0.
- The finish does not taper. Keep Bloom running and feed at full EC to the end — Athena print “DO NOT TAPER EC” in capitals. Then rinse through with RO and Cleanse: one day in rockwool, up to three in coco.

Common questions
Blended or Pro — which should I buy?
Blended is liquid and mixes straight into a tank, which suits most tents and small rooms. Pro is a powder you mix into a concentrate first, and it pays off when you are filling large reservoirs regularly. The nutrition is Athena's either way.
Where is the Pro Line chart?
Athena publish the Pro schedules as downloads on their own help centre rather than as a web page. Their Pro Line page is here. Note their imperial and metric versions assume different concentrate dilutions.
Athena's EC looks high next to other brands.
It is, deliberately. Athena hold a steady EC and vary what the plant receives through irrigation frequency rather than tank strength. Coming from a brand that ramps, move gradually and watch runoff.
What if my run is longer than nine flower weeks?
Athena's answer is to repeat the formula for a longer veg, and their chart note says to adjust the schedule to the number of weeks your run actually takes.
