Feeding Tips

-ml per 1 US gallon (unless otherwise noted)
-These rates are based on distilled water. Water quality will vary and may increase the PPM/EC.
-This chart is a basic guideline. Use recirculating or runoff PPM to adjust as needed.
-If using a recirculating system, amended media, or feeding multiple times a day, reduce initial feed rates by 25%.
-Measure the PPM of runoff weekly; runoff should be within +/- 20% of initial feeding.
-For longer vegetative cycles, continue week 4 feeding.
-For longer reproductive cycles, continue week 4 feeding.
*1 mL/gal of E-PLUS may be used throughout flowering if additional nitrogen is needed.

pH Tips

-These products are most effective when the pH is unadjusted.
-If pH falls below 3.0, adjust with potassium hydroxide; do not use potassium carbonate or potassium silicate (pH of 3.0 or lowermay result in nutrient deficiency).
-If pH rises above 6.0, adjust with phosphoric, nitric or sulfuric acid.
-Using an air stone in a standing reservoir is not recommended with ourproducts, as they contribute to rapid rise in solution pH. Gentle agitation, such as with a recirculating pump, can be used if agitation is required.

READY TO USE SOLUTION

PART A 2.5 2.5
PART B 4.5 4.5
PK 0 2
PPM (TDS/500) 1040 1260
EC (mS/cm)/500) 2.08 2.52
  • PPM and EC of the chart are based on RO water with <0.2 PPM. The EC of the solution will vary depending on the starting EC and water quality of your particular facility. No pH adjustment is necessary if solution pH is no higher than 6.0.
  • Non RO water registering above 7.5 pH should be adjusted below 7.0 pH before adding nutrients.
  • Part A, Part B and PK can be mixed in any order.
  • Part A, Part B and PK are incompatible when mixed individually at concentrations exceeding 100x the ready-to-use rate.
  • Stored water or on demand water should be pre-adjusted to 5.8-6.0 for all of your watering needs.

Figures above correspond to total gallons of each product required per cycle.

Note: the logic shows the total gallons of each product used per week - nothing else.
