These mixes work well and are the accepted standard mix recommended for newbies as well as those new to GH Flora series nutes. It is simple to remember: 3-2-1...2-2-2...1-2-3. Listed as (grow-micro-bloom) Always mix the micro into the water first.
**Teaspoons per US gallon (5ml = 1 part)
Vegetative stage: Use 3-2-1 (3 parts grow, 2 parts micro, 1 part bloom)
Early flowering: first 2-3 weeks or until stretching stops: Use 2-2-2 (2 parts each)
Late flowering: Use 1-2-3 (1 part grow, 2 parts micro, 3 parts bloom)
** Dilute final mixture (or adjust part size) to suit your plants nutrient strength (EC/TDS) requirements. GH Flora series is slightly lacking Mg, add 1/8 to 1/4 teaspoon epsom salts per gallon of final mix. Dissolve the salts in some warm water before adding to your nutrient reservoir.
