Marijuana Bloom Fertilizer

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.

    Buds seemed to fatten up nicely during the Bloom stage. Can’t wait to start my 2nd grow with this Reefertilizer product.

    I’ve started using the bloom fertilizer on my indoor plants and I can see the size of the buds is already bigger than crops before at this stage. Will always use this product!!

    Very happy with the product so far … First time using powder nutrients and haven’t had a chance to use the bloom nutes yet. The grow nutes however have noticeably been very well received by the plants and have no issues with nutrient burn.

    Will definitely purchase again!

    Very happy so far! I started using the nutrients on June 18th and my tallest plant was about 18″.

    Its Aug and my tallest are now over 72″! I really found the plants produced alot more consistent/ hearty branches after starting the system.

    I’ve got a few on the Bloom now and are stacking up nicely!

    Happy growing!
