Feeding Tips
All Feeding Charts and application recommendations are not definitive instructions. All crops and genetic strains within plant species have different metabolism rates. Some strains are genetically predisposed to be heavy feeders and others are light feeders. There are also environmental conditions that provide for higher metabolism rates (CO2). This makes it difficult for us to provide set in stone instructions. We recommend that all gardeners research their favorite strain and learn what it likes. More importantly, pay attention to what your plants are telling you.
For best results: Always use unchlorinated water. Maintain pH levels between 5.5 – 7.0 and check reservoir after adding all nutrients. Due to our use of multiple chelating agents in our formulas, the elements within our products can be absorbed by plants in a wider range of pH levels.
Oxygenate water before and during application. To prevent nutrient settling, always use a pump at the bottom of the reservoir to continually agitate and mix the nutrient water during application. Research and development conducted using water obtained by reverse osmosis (RO) containing a near 0 parts-per-million (PPM).
PPM is a measurement which is affected by a number of factors including the soil or medium, the environment, water cleanliness and quality, age of water filters, and nutrients introduced into the environment. For that reason you cannot be too dependent on PPM to judge garden health. For most plants, in most gardens, our feeding charts during Grow Weeks One through Four will range from about 400-500 PPM in Week One to about 600-800 PPM during Week Four. During the Bloom Weeks our programs will range from about 700-900 PPM in Week One to a range of about 1300-1600 during Week Six, with a drop to about 1200-1300 PPM in Week Seven.
If PPM is too high at any stage of growth, add RO water to decrease the PPM to desired level.
Foliar Charts
Conventional Foliar Feeding Schedule
Natural Foliar Feeding Schedule
Oneness Program
8 Week Hydroponic
8 Week Soil
Basic
For best results: The Oneness Program works excellently in all growing applications: ebb & flow (re-circulating), drain to waste, soil, soilless, aeroponic, deep water culture, and fogponic systems, using any growing media or garden setup. If using an ebb & flow system, drain your reservoir every 5 – 7 days then clean your equipment and pumps, and remove any filmy buildup on the reservoir itself.
Premium 2-Part Program
8 Week Hydroponic
8 Week Soil
Basic
3-Part Conventional Program
8 Week Hydroponic
8 Week Soil
Basic
For best results: Humboldt Nutrients complete hydroponic feeding schedules work great with re-circulating, drain to waste, and all other growing methods. If using an ebb & flow system, every 5 – 7 days drain your reservoir then clean your pump and equipment.
Organic Program
8 Week
10 Week
Basic
For best results: Humboldt Nutrients organic feeding schedules work best in soil applications. For optimum biological activity which fixates and increases availability of nutrients, combine nutrients and additives with water and allow to “brew” for at least 24 hours prior to use.
All-Purpose Additive Program
This all-purpose additive program was designed to improve performance when used to supplement any Base Nutrient system on the market.
