Athena Feed Chart: Blended and Pro Line Schedules (Metric)
Greens Horticulture ·
The Athena feed chart, from Athena's own metric schedules. There are two programmes: the Blended Line (liquids, used by most growers) and the Pro Line (powders, made for larger rooms with dosing systems). Athena give both in per 10 litres of water: divide by ten for per litre.
Athena Blended feed chart
All doses are ml per 10 litres. Mix in the order the rows are listed, top to bottom: Athena put Grow B before Grow A, and Bloom B before Bloom A.

pH and the extras
- pH: 5.6 for cuttings; 5.8-6.2 in coco or rockwool and 6.0-6.4 in peat-based mixes through veg and flower; 6.0-6.4 for everything in the last flower week.
- Athena Balance is used as a pH up. Athena recommend it for batch tank mixing and Dosatron, not for Netaflex.
- Pre-soak 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.
- Flush: plain RO water with 26 ml of Cleanse per 10 litres (EC under 0.1, pH 6.0-6.4) - the last 3 days in coco, the last day in rockwool.
Athena Pro Line feed chart
Pro Line doses are grams per 10 litres; Cleanse and Fade are ml per 10 litres. Athena recommend mixing the powders into a concentrate first rather than weighing them into each tank.

- * Swap Pro Core for Fade in flower weeks 8-9; how early depends on the plant. If it is standing up well, Athena say you can use Fade (51 ml per 10 L) from week 7. Check the pH when you switch.
- Pro Balance is the pH up for advanced irrigation systems such as Netaflex; the Blended Balance is for batch tanks and Dosatron.
- pH, pre-soak and flush are the same as the Blended programme above.
Notes from Athena
Athena describe both charts as a baseline: adjust the number of weeks to fit your run, and expect some plants to want more or less.
What you need
- Athena Grow A & B, Bloom A & B, PK, CaMg and Cleanse for the Blended programme.
- Pro Grow, Pro Bloom, Pro Core and Fade for the Pro programme.
- pH and EC meters - both programmes are written around EC.
