Athena Feeding Schedule

About Athena

Athena was built for commercial cultivation first and everyone else second, and it shows in the product design. The lines are deliberately short, the labels are plain, and the schedules fit on one page. There is no additive upsell ladder here — the philosophy is that a well-built base feed plus clean water gets you most of the way, and complexity is a liability at scale.

That focus has made Athena one of the fastest-moving brands we stock. It suits growers who want repeatability more than experimentation, and it is genuinely easy to run in a room with more than a few plants.

The feed chart

Blended Line

These are Athena's own published figures for the Blended (liquid two-part) program, set out so you can read them on your phone in the grow room instead of pinching around a PDF. The chart runs Clone through Flower week 9 in mL per gallon.

Balance is not on a weekly dose. Athena lists it as a pH-up adjuster — use it to raise pH when you need to, at any stage. Their chart carries one caution with it: recommended for batch tank mixing and Dosatron, and do not use it with a NetaFlex.

Target pH by growth stage

Athena's chart gives a separate pH target for Coco/Rockwool and for peat-based mediums during Veg and Flower. This is not tied to a specific week — it applies for the whole stage named.

Target pH — by stage and media
Stage Target pH
Clone (all media) 5.6
Veg – Coco/Rockwool 5.8-6.2
Veg – Peat-based mediums 6.0-6.4
Flower – Coco/Rockwool 5.8-6.2
Flower – Peat-based mediums 6.0-6.4
Flush (all media) 6.0-6.4

A dash means Athena's chart does not call for that product at that stage. It does not mean add plain water instead of feeding — other rows may still show a dose for that same week.

Figures as published by Athena Ag, Inc. (document Blended_Feed_Schedule_Imperial, Athena reference A01.004). Feeding charts are recommendations only. Adjustments may be needed based on environmental conditions, your grow structure, and any additional products you run. Actual results vary.

The table above covers the Blended Line Imperial schedule. This is Athena's own PDF, hosted here so the link does not rot:

Lines we carry

  • Pro Line — dry soluble powders (Pro Core, Pro Grow, Pro Bloom). The most cost-effective way to feed a large room
  • Blended Line — liquid two-part for growers who would rather not mix powders
  • Fade — the late-flower finisher, and the reason those charts have a Fade column
  • Balance, Cleanse, Stack, Bloom Core — the short list of supporting products
  • Culture Media — for tissue culture and propagation work

Reading the schedule

Athena's charts run in grams per gallon for Pro Line and mL per gallon for Blended, so check which chart you have in front of you. Mixing order matters: Balance first if you are using it, then Core, then Grow or Bloom.

The Fade column at the end is not optional garnish — it is how the program is designed to finish. Growers who skip it usually report a harsher result.
