| Stage | Grow A (mL) | Grow B (mL) | Bloom A (mL) | Bloom B (mL) | Silica (mL) | Super PK (mL) | CCS (mL) | EC guide |
|---|
Mixing order: Water → GT Silica (if used; stir and allow to rest) → Grow/Bloom A (stir) → matching B (stir) → other additives → check EC → adjust pH last. Never mix concentrated A and B directly.
pH: Aim around 6.0; classic GT Coco guide 5.8–6.5; current manufacturer guidance 5.5–6.5. Follow your product label where it differs.
Important: Rates are indicative starting points from the classic feed chart, not fixed prescriptions. EC assumes reference water conditions; check the actual solution. For cuttings, CCS is used instead of Coco A/B. Current product directions may differ.
