When I am consulting, I get asked for a complete but cheap nutrient lineup that is suitable for commercial usage. This lineup can also be scaled for the home grower to save some serious cash.

You start with a salt base nutrient. Jack's classic hydro, Masterblend, Jack's Nutrients TAP or Growmore soluble powders also work depending on your access.

Jack’s Hydro Feed- 25 lb bag
$70- 2000 gallons
$0.035/gallon

Add your biostimulant. Mr. Fulvic is the home and garden version and has fulvic, amino and organic acids, chelated micros and trace elements. AGT-50 is the commercial wholesale version. They both help make nutrients available regardless of pH and give salts organic taste and smell.

AGT-50- 20L
$460- 20,000 gallons
$0.023/gallon

Extra calcium is needed at transition. Growmore Flowering Cal-Mag also has kelp to help stack nodes going into flower. Albion metalosate and epsom salt can also be used.

Growmore flowering cal-mag- 2.5 gal
$90- 1900 gallons
$0.047/gallon

PH down is pH control, but also adds soluble phosphorus when something like HydroFeed is low in Phosphorus.

Advanced pH down- 4L
$82- 6600 gallons
$0.01/gallon

For IPM, insecticidal soap will take care of bugs and mold.

DES-X Insecticidal Soap- 2.5 g
$85- 300 gallons (@1%)
$0.28.3/gal.

For a bloom booster, Monopotassium phosphate used weeks 4-6 of flower.

Haifa MKP- 4 lb
$20- 1820 gallons
$0.01/gallon

This is a complete lineup including IPM. It can be used large or small. There's no reason to spend a ton of money on fertilizer for excellent quality cannabis.

I typically use rice hulls, DE or Recycle Sil in the soilless mix, but if you want to add silica-


Potassium silicate- 20 lb
$160- 1820 gallons
$0.087/gallon

[eyesdownchronic]

do you use calnit at all?

[BillFarthing]

Cal Nit is always part of your base fertilizer whether it is one, two or 3 parts. It is certainly part of Jack's Hydrofeed, TAP, Classic Hydro or Growmore solubles.

Gday have you ever tried masterblend nutrients. A same as Jack's as in it's a 3 part dry.

Yeah, I listed it as part of the salt bases that are economical. Masterblend/cal nit as a 2-part has fantastic numbers without the magnesium sulfate.

You add RecycleSil to the mix? At what rates? Doesn't it get washed away within the first few waterings?

1 tablespoon to a 15-gallon pot of soil or soilless media. It can be suspended in water, but isn't totally soluble, meaning that it won't wash out from the root zone easily.

Bill thanks for this.
Can you talk about how the schedule? How do you advise to tweak the ingredients throughout the grow? Or is this more like the lucas system where the the ratios stay the basically same veg and bloom.
Hope that doesn't sound stupid

[BillFarthing]

The only stupid question is one that doesn't get asked.

-Follow the feed schedule on your salt base. It essentially ramps up EC from seedling/transplant -> veg -> transition -> bloom and cuts out for flush.

-Mr. Fulvic/AGT-50 is always 0.5-1ml/gallon drench from transplant through harvest.

-Supplemental calcium is used right before flip either drench or foliar until they stop stretching or show flowers. Usually 1-2 weeks.

-Bloom booster is used week 4-6 of flower. I listed MKP, but I also like the homemade Hammerhead recipe.

-pH Down is used as needed to keep the pH 5.5-6.2.

-Insecticidal soap is used 15-60ml/gal. with Mr. Fulvic at 0.5-1ml/gallon foliar veg through transition. The fulvic makes the soap trans-laminar and provides foliar stress reduction.

This method exactly follows the tissue sample graphs that I always post from Agricen.
