All-in-One Cannabis Flowering Fertilizer

Our Reefertilizer™ marijuana Bloom fertilizer formula is the final step of our fertilizer and nutrients program designed for mature plants. By introducing calcium – as well as increasing the amount of phosphorus available to your plant – you will encourage the growth of strong and healthy marijuana buds. Reefertilizer™ Stage 3 formula will help your plants realize their full flowering potential.

During the bloom stage of your grow, marijuana plants will be using nutrients to build flowers and buds. A good marijuana grow fertilizer contains calcium which helps in this bloom process. By maintaining a balanced feeding schedule and leeching your soil of nutrients and fertilizer a week before harvest, you should obtain large bountiful tasty buds.

Questions and Answers

Is this product organic or synthetic?
Reefertilizer Bloom would be considered a synthetic fertilizer. Reefertilizer Bloom contains chelated nutrients; which are inorganic metal nutrients that are encased by organic molecules. They are immediately available to your plants and don’t need time to break down compared to organic fertilizers.

Will synthetic fertilizer harm microbes in my soil?
Microbes in soil feed off the same elements available through organic or synthetic nutrients. Avoiding over-fertilization and maintaining the right soil pH will keep soil microbes happy.

What makes this flowering fertilizer different from “other brand”?
Reefertilizer tries to simplify the growing process by providing a full range of macro and micronutrients that aid with plant-specific growth. By blending these together as a water soluble powder, it will save you time and money compared to using multiple products.
Reefertilizer Bloom is low on nitrogen which is important during flowering, and it has a little extra calcium and magnesium which is a common nutrient deficiency in flowering plants.

When do I start feeding my plants Reefertilizer Bloom?
When you start to see flowers begin to form around the nodes (where the branch meets the stem) you can switch to feeding your plants Bloom. For autoflowers, this is usually 3 or 4 weeks in. For outdoor plants, this is usually around July or August in the northern hemisphere.

How much do I feed my plants?
Start with 1 scoop (5ml) for every 4L (1 gallon) of water. Feed each plant weekly with enough of this solution to fully saturate the soil and have a bit of runoff. You can water your plants as needed in between feedings. Some folks split the dose and feed twice a week. Both work fine, pick whichever method is easier for you.

Can I pre-mix these nutrients?
Because these are chelated nutrients they don’t do well being mixed into water and stored for long periods of time. The elements within the solution can react with each other and lower the effectiveness of the fertilizer. A few days is okay, but anything longer than a week might not be a good idea.
