NPK Industries Feeding Schedule
About NPK Industries
NPK Industries makes the products you reach for when something has gone wrong. Raw is the range most people know — single-element soluble powders (Raw Cal-Mag, Raw Silica, Raw Nitrogen, Raw Phosphorus, Raw Potassium, Raw Humic, Raw Kelp) that let you correct one deficiency without disturbing the rest of the feed.
Alongside that sits the Pro-Line and the Zone / Cannazyme-style cleaners. It is a diagnostic brand more than a programme brand: you keep a shelf of it and use what the plant is asking for.
The feed chart
These are NPK Industries’ own published figures, transcribed from the manufacturer’s image files so you can read them on your phone in the grow room instead of opening a PDF. Four charts are covered: the GROW/BLOOM soil schedule, an individual-RAW-products reference (each product’s own rate on its own — not meant to be run all at once), a PPM-equivalent reference for the RAW line, and the Mother Plant feeding schedule.

A dash means NPK’s own chart lists nothing for that product at that week/column.
Mother Plant Feeding Schedule footnotes (NPK’s own numbering): 1. Humic Acid: If using Humic Acid without Full Up, increase dosage until it is double that of Kelp. · 2. Kelp: Kelp works 50% better when combined with Humic Acid/Full Up. · 3. Yucca: Yucca is an excellent wetting agent for drench and foliar sprays. Use at very low doses. · 4. Silica: RAW Silica is an organic, pH neutral silica source derived from diatomite. · 5. Full Up: If using Full Up without Humic Acid, increase dosage until is double that of Kelp. · 6. Cane Molasses: Use Cane Molasses when in soil along with Microbes Grow Stage. · 7. Nitrogen: Nitrogen may be used at the roots or as a foliar feed at low dose to treat Nitrogen deficiencies if they appear (general chlorosis).
Source-file note: the Mother Plant PDF prints the “Structure” row’s product as “Clacium / Mag” (letters transposed). We have published it as Calcium / Mag — the spelling NPK itself uses correctly on the other three charts on this page — and are flagging the source typo here rather than repeating it.
The PPM Values chart also lists a row exactly as “ominA” in NPK’s own file. We could not match that name to a product named elsewhere on NPK’s own charts or in our RAW lineup, so it is reproduced verbatim rather than guessed at.
These four charts are all published by NPK Industries as flattened image files with no text layer to extract, so the figures above were transcribed by eye directly from the manufacturer’s own PDFs (documents grow_and_bloom_in_teaspoons, individual_raw_products_in_teaspoons, PPM_Values_of_RAW_products_in_1_Gallon_of_water and mother_plant). Feeding charts are recommendations only. Adjustments may be needed based on environmental conditions, your grow structure, and any additional products you run. Actual results vary.
