Just Getting Started with Seedlings?

Buying and using nutrients should be simple, honest, and cost effective. The nutrients for our favorite plant should include all of the essential elements, come in only a few or no bottles, and provide you with the ability to improvise and control the process. This is why we came up with a simple two part formula for both the Vegetative and Bloom stages. All of the essential elements included in these products have been documented for you to see. And, we made sure we sourced high quality elements at the best pricing available so we could pass those savings on to you. For more info on how the first FloraFlex Nutrient line evolved, read our story.


Mixing Instructions

V1™ & V2™

  • First Mix V1 in your water source, allow it to completely dissolve. Then add V2.
  • Depending on your desired EC use 1-2 teaspoons per 5 gallons of water (1-2 grams per gallon)
  • Add V1 and then V2 to your water source throughout the entire vegetative stage.
  • At lower dosages V1 and V2 can be used as a base along with other additives.

Formula Details

Formula EC

All formulas are meant to have a starting water EC of 0.2 – 0.3, you can get up to, but should not exceed, an EC of 0.7 – 0.8. If you are using RO water with an EC of 0 then bring your EC up to 0.2 – 0.3 by adding hard/tap water, but most people find success by adding a Cal-Mag. Pure water with no dissolved salts has no buffering capacity and therefore the pH is difficult to predict or control. Blending in some municipal water usually adds a little bicarbonate which gives a little buffer capacity to the water making pH control easier.

Formula pH

While the pH of your fertilized water going into the medium is important, many agree that the water inside and/or coming out of your medium/drain water, what the roots are uptaking, is of the utmost importance. The pH of your drain water should be maintained between 5.3 – 6.3 to maximize your plants ability to absorb the necessary nutrients. Our nutrients have been tested in different water sources and mediums, and were found to consistently remain between these optimized levels.

Additive Use

If you are utilizing other additives with no NPK values then you will keep the amounts of suggested rates. But if you are adding other additives with NPK values, you should decrease the amount of FloraFlex Nutrients. Keep in mind we have formulated these blends to not need any additional NPK value.

Flush Information

Some growers flush weekly in Bloom, others do it a few times on designated days (before and/or during traumatic or stressful occurrences such as defoliation), while some only flush when they see the plants starting to show signs of excess salt build up within the medium or stress signs from their plants, such as the edges of the leaves spiking up. If and or when you flush use a lower ratio of fertilized water between 0.7 – 1.0. Ideal water temperatures for your fertilized water are in the range of 60° – 75°.


All Micronutrients will be found in parts 1. If you ever experience micro deficiencies scale back like the formula until your plants look healthy again. The first week of Veg and the first of Bloom should do the trick if you have issues.
