-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.
-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.
