Everyone wants them — but not many achieve it.

In this tutorial, we’re going to teach you how to use bloom boosters safely and efficiently to ensure a record-busting yield of trichome-packed marijuana flowers.

Unlike other online guides, we believe bloom boosters are an excellent tool to increase your overall yield. However, we acknowledge that many new cannabis cultivators go overboard when introducing bud enhancers into the garden.

Therefore, let’s dig deep on the topic of bloom boosters and learn how to use bud enhancers without burning your weed crop.

What Are Bloom Boosters and Why Are They Important?

Bloom boosters are concentrated forms of nutrients — specifically P and K.

In general, bloom booster products come in liquid or powdered form. Remember, the keyword of bud enhancers is that they are concentrated. In other words — a little bloom booster goes a long way.

Phosphorus and potassium play significant roles within cannabis plants — especially during the flowering process. Alongside nitrogen, P and K are known to stimulate the flowering response dramatically.

For those who are curious, phosphorus and potassium increase:

  • Overall yield (biomass)
  • Resin density
  • Cannabinoid content
  • Terpene content

As you can see, bloom boosters don’t only focus on improving yield. Instead, bloom enhancers have a multi-beneficial outcome by also elevating the terpene and cannabinoid profile.

Therefore, bloom boosting nutrients for weed plants are a no-brainer when you want to stack on the ounces!

The Dangers of Using Bloom Boosters For Marijuana Plants

Now, it’s time to learn about the potential pitfalls of harnessing the concentrated nutrients within bloom booster products.

Remember, too much of a good thing is usually bad. Although your weed plants will enjoy the steroid-like response, bloom boosters can harm your marijuana plant if given the incorrect dose.

Nutrient Burn Cannabis

If you provide too much bloom nutrient, your cannabis may become:

  • Burned (nutrient toxicity)
  • Stunted (slowed growth)

In both cases, a reduced yield and a significant drop in plant health is the outcome. Sudden death is also a possibility in some extreme cases of overfeeding with PK boosters.

Ultimately, it’s because of PK booster’s intense concentration that makes them daunting to use — especially for beginners.

Luckily for you, we’ve created this guide on bloom boosters to make sure you learn how to apply bud boosters the right way to avoid any problems down the road.

When Is The Best Time To Use Bloom Boosters On Weed Plants?

It goes without saying that there’s a window of opportunity to apply bloom boosters on your cannabis crop.

Whether you grow weed indoors or outdoors — the best time to use bud enhancers is during the flowering stage. However, the critical moment to use bud booster nutrients is during:

  • Weeks 2, 3, and 4 of flowering

By providing bloom-boosting nutrients during the early half of flowering, you’ll stimulate a significant bloom response that snowballs into a bumper-busting harvest by the end of the flowering process.

Remember, cannabis plants need to metabolize the nutrients, and you don’t want to give bloom boosters too late or too early.

How Much Bloom Booster Nutrient Should You Use?

Each bloom booster nutrient instructions vary depending on the brand that you choose.

However, you must follow the product’s directions. If the bloom booster from brand “x” says to apply 2mL of bud enhancer per liter of water once during weeks 2,3, and 4 — do not deviate from their instructions!

Overall, it’s a great idea to practice a bit of prudence when using ultra-concentrated bud boosters. In other words, we always recommend giving half of the recommended dosage and monitor your pot plants.

Once you feel comfortable and your cannabis plants do not exhibit nutrient toxicity signs (burning) — you may use the recommended dose on the brand’s instructions.

What About The Rest of The Feed Schedule?

If you’re wondering what happens to the rest of the feed schedule — the answer is nothing.

Remember, bloom boosters are supplemental nutrients. Your primary nutrient product, such as Bloom A or Bloom B (base nutrients), are still used normally.

This is why you must monitor your cannabis plants during the duration of using bloom-boosting nutrients.

As long as you follow the feed schedule from your base nutrients and bud enhancing supplements — you’ll be well on your way to a scale-tipping weed harvest!

How To Use Bloom Boosters on Cannabis Plants in Five Easy Steps

Ok, now let’s talk about how to apply your bloom boosters.

There’s no better way to learn something than getting your hands dirty — so let’s go!

Before we begin, let’s make sure you have the correct materials for the task. To properly use bloom nutrients, here’s a quick rundown of what you’ll need:

  • pH meter
  • Nutrient meter
  • Mixing cup
  • Water (preferably filtered)
  • Bloom booster fertilizer (liquid or granular)
  • Plastic applicator/syringe
  • pH up and down solution

Once you have all of your materials — head over to step one.

Step One: Timing

Cannabis Bloom Booster Timing

First and foremost — ensure that it’s the correct time to apply bloom boosters and that your cannabis plants are healthy.

Therefore, if the bloom fertilizer instructions say that you must begin the regimen during week 2 — make sure it’s the second week of flowering!

Furthermore, you must ensure that your marijuana plants are healthy. Why? Because unhealthy plants may be sensitive to a concentrated dose of P and K.

By growing healthy and happy weed plants — they’ll gobble up every last drop of P and K to produce stellar buds.

Step Two: Read the Instructions

Next, it’s time to read the instructions to determine the serving size.

For example, the bud enhancer label specifies that you must mix 2mL of nutrient per liter of water.

Great! If you want to feed your marijuana plant the full monty — 2mL per liter of water is where you begin. However, if you wish to err on the side of caution, you may start with 1mL of bloom nutrient per liter of water.

Step Three: Mix

Once you determine the dosage of bloom booster — it’s time to create the mixture.

Use the plastic applicator (if liquid) or use a scale (if granular) and measure the correct amount. Once done, place it in a mixing container.

Next, gather the corresponding amount of water, such as one liter. In our experience, distilled or filtered tap water works best.

Step Four: Measure pH and Nutrient Content

Once you’ve created your bloom booster nutrient solution — it’s time to measure the pH and nutrient content.

At this moment, take out your pH and nutrient meter to ensure the solution is in the proper pH and nutrient range.

If you’re a little rusty on how to use a pH or nutrient meter, let alone calibrate them, take a refresher course and read our guides — Why You Need to Use a pH Meter When Growing Weed in Hydroponics, How to Calibrate and Use a pH Meter, and How to Calibrate and Use a Nutrient Meter.

Once the bud enhancer nutrient solution meets the pH and nutrient criteria — move on to the final step.

Step Five: Feed

Now that your bloom-boosting nutrient solution is locked and loaded — it’s time to feed your cannabis plant(s).

Whether you use a watering can, drip line, or reservoir — place the bloom booster solution into your irrigation method of choice and let it rip!

Remember, once you feed your green beauties with bud booster — you must monitor the plants for the next 12-24-hours.

Do your cannabis plants look happy? If so — great job! However, if the leaves’ edges exhibit burned or curled sections — you may need to decrease the dosage next week.

If your cannabis plant continues to look sad — you may need to flush your cannabis plants to avoid nutrient lockout. If you don’t know how to flush your cannabis plant — worry not!

You can read our guide one flushing here — How to Flush Cannabis Plants.

Remember, all marijuana strains are different. Some weed plants are picky eaters, while others will take anything your throw at them. Therefore, you’ll need to experiment to see what dosage works best for your cannabis crop.

Kick Back And Watch The Buds Stack

Once you’ve completed the bud enhancer regimen — it’s time to kick back, relax, and watch the buds stack.

Remember, the point of feeding weed plants concentrated phosphorus and potassium is to stimulate a response. In the case of marijuana, the response is:

  • Bigger buds
  • More resin
  • Higher cannabinoid levels
  • Elevated terpene content

Whether you’re growing cannabis indoors, outdoors, hydroponics or soil — the result of a correctly applied bloom booster is a lot of top-shelf buds.

Once harvest time comes around — don’t say we didn’t warn you! From long trimming hours to ultra-sticky fingers, you’ll find an overwhelming harvest that’s jam-packed with ounces of excellent weed.

My hubby fried our plants with to much bloom food.
Lost 1/3 of the leafs.
He has flushed them , trimming dead leafs.
Should we skip watering and feeding for a day?
