Earth Juice / Hydro Organics Feeding Schedule
About Earth Juice / Hydro Organics
Earth Juice is one of the oldest organic lines in the trade. Grow, Bloom, Catalyst, Meta-K and Microblast are the classic bottles — unrefined, genuinely organic, and famous for needing a stir and a settle before you use them. The pH swings on their own as the biology works, which is normal for the line and catches new users out.
Hydro Organics is the same house. If you want organic inputs and you are prepared to work with a product that behaves like a living thing rather than a salt solution, this is a good place to be.

N/A is the manufacturer’s own chart marking that formula as not used during that stage.
This PDF sheet also prints a second, “Original with Big Bloomin’” chart (Grow, Big Bloomin’, Xatalyst, MetaK, Microblast) as an alternate to the table above; that variant has no download link of its own on this page, so it is not reproduced here.

| Product | Rate | Recovery Systems | Non-Recovery Systems | ||
|---|---|---|---|---|---|
| tsp/Gal | mL/L | tsp/Gal | mL/L | ||
| Vegetative | Starts | 1 tsp | 1.3 mL | 0.75 tsp | 1 mL |
| Mild | 2 tsp | 2.6 mL | 1 tsp | 1.3 mL | |
| Medium | 4 tsp | 5.3 mL | 2 tsp | 2.6 mL | |
| Strong | 6 tsp | 8 mL | 3 tsp | 4 mL | |
| Transition | Mild | 2 tsp | 2.6 mL | 1 tsp | 1.3 mL |
| Medium | 4 tsp | 5.3 mL | 2 tsp | 2.6 mL | |

| Strong | 6 tsp | 8 mL | 3 tsp | 4 mL | |
| Grand Finale | Mild | 2 tsp | 2.6 mL | 1 tsp | 1.3 mL |
| Medium | 4 tsp | 5.3 mL | 2 tsp | 2.6 mL | |
| Strong | 6 tsp | 8 mL | 3 tsp | 4 mL | |
“Product” is Sugar Peak’s own four-stage line — Vegetative, Transition, Flowering and Grand Finale are separate bottles used one after another, not four doses of one formula.
Every stage happens to share the same Mild/Medium/Strong dosing on the manufacturer’s own chart; only the Vegetative bottle adds an extra, lower “Starts” rate for young plants.
SeaBlast

| Feed type | Rate | Grow | Transition | Bloom | |||
|---|---|---|---|---|---|---|---|
| tsp/Gal | gm/4L | tsp/Gal | gm/4L | tsp/Gal | gm/4L | ||
| Constant Feeding | Mild | 1/8 | 0.63 | 1/8 | 0.63 | 1/8 | 0.63 |
| Medium | 1/4 | 1.25 | 1/4 | 1.25 | 1/4 | 1.25 | |
| Strong | 1/2 | 2.5 | 1/2 | 2.5 | 1/2 | 2.5 | |
| Injectors | 9 oz | 270 g/m | 9 oz | 270 g/m | 9 oz | 270 g/m | |
| Periodic Feeding | Mild | 1/4 | 1.25 | 1/4 | 1.25 | 1/4 | 1.25 |
| Medium | 1/2 | 2.5 | 1/2 | 2.5 | 1/2 | 2.5 | |
| Strong | 1 | 5 | 1 | 5 | 1 | 5 | |
| Injectors | 18 oz | 540 g/m | 18 oz | 540 g/m | 18 oz | 540 g/m | |
SeaBlast doses the same rate across Grow, Transition and Bloom on the manufacturer’s own chart — it is not a phase-sensitive formula.
“Injectors” is the manufacturer’s own dosing row for injector/proportioner setups. Its gm/4L figures print as “g/m” in that row on the source chart, a shorthand of the same unit the Mild/Medium/Strong rows spell out in full; reproduced here exactly as the chart shows it.
All four charts on this page are genuine text PDFs (not scanned images), so every figure above was pulled straight from the manufacturer’s own file, not typed by hand. Feeding schedules are recommendations only; adjust for your own water, medium and environment.
