Stock-solution targets for propagation

Soak clone plugs in the prepared propagation feed before inserting cuttings. Keep the substrate evenly moist while roots establish. Avoid aggressive dry-backs during this stage so the plugs retain enough moisture for developing roots.

Vegetative growth stage targets.

Record root-zone EC and pH early in veg so you can spot changes as irrigation demand increases. As roots expand, increase irrigation as needed and allow enough dry-back between events for root-zone oxygen. Watch stem firmness and the spacing between nodes. Soft growth or excessive stretch is a reason to review nitrogen and irrigation together. For extended veg, start with the Standard Vegetative recipe and consider stepping up to High EC later if crop response and growing conditions support it.

Transition/early flowering targets.

Start Bloom and Late Bloom together with Calcium + Micros. During weeks 2 and 3, watch stretch and stem firmness, and check root-zone EC, pH, and moisture for signs that salts are accumulating or the substrate is staying too wet. If excessive nitrogen or irrigation is contributing to stretch, review irrigation and consider moving to the lower-nitrogen Mid Flower recipe one week earlier. For an eight-week flowering schedule, skip Early Flower week 3 and move directly from week 2 to the Mid Flower recipe.

Peak flower development targets.

Check root-zone EC and pH closely as flowers bulk and nutrient demand peaks. Compare readings over time so you can respond to changes in the root zone as they develop. Maintain airflow and humidity that support transpiration, which helps move nutrients through the plant during this period of high demand.

Late flower bulking targets.

Continue both Bloom and Late Bloom at the listed rates as the chart tapers nitrogen. A gradual, even fade can accompany that taper. If color changes are patchy, check root-zone EC and growing conditions before cutting feed further. Keep watching for salt accumulation as feed strength falls. The guide recommends about 10–14 days on the Late Flower recipe before moving to Finish.

Finish / pre-harvest targets.

Use Late Bloom and Calcium + Micros at the listed Finish rates. Late Bloom itself contains no nitrogen, and Calcium + Micros continues to supply nitrogen in the Finish recipe. The guide presents this recipe as an option for shortening or replacing a plain-water flush. Watch how quickly fan leaves change color. Some fade is expected in many cultivars, while the leaves should remain functional through the final stages of flower development. Check trichome maturity when deciding when to harvest.
