    First time user and had great results for the “Grow” phase! It was easy to measure with scoop included with Grow Reefertilizer.
    Would have loved to try the Bloom Reefertilizer, but they’ve been sold out for a while… Couldn’t wait.l, sorry ;(…

    I have another Bakerstreet Indica plant under way and it’s now 57 days old. It’s in a 1.75 Gallon pot and is under a FLUVAL 6500K Plant Spectrum LED System. I administer 1 litre of water with one teaspoon of the Grow Compound once a week. The leaves on the plant actually start to stand up at around 07:00 PM every night and stay that way until 06:00 AM the next morning. I read an article that said that this means the plant likes what is being done. I did see “Clawing” on the Fan Leaves so last week I flushed the plant with straight water (Ph level 6) and it’s been doing well. I resumed the watering once again this morning after 7 days with one litre of water mixed with one teaspoon of Grow Compound and the plant looks good. I have provided two photos for your assessment.

    So far not so good. To start it took 5 minutes of digging around in the bag to find the measuring scoop included (not the end of the world, but having it attached to the outside of the bag would have been more convenient). I’ve noticed in the GROW formula, that the calcium nitrate pellets have mostly settled to the bottom of the bag, making for an inaccurate NPK ratio, causing a heavy nitrogen deficiency in my plants, to which I supplemented with calcium Ammonium nitrate. I feel using powdered calcium nitrate would have been a better option to help keep NPK ratios proper. Everything else seems to be in check tho… will continue to use for this grow, just watching the nitrate levels a little closer.

    Constant nitrogen deficiency

    • Avatar

      Mike Drouin (store manager)

      I’m sorry to hear this. Nitrogen can be locked out when the pH of the medium is not in the correct range (between 5.5 and 6.5). This and overwatering are the most likely causes for signs of a nitrogen deficiency. I hope you decided to give it another try in the future. Cheers!

    I apply the fertilizer once a week as recommended, and, the results have been fantastic. Tons of new growth and bushy healthy plants. All my friends who also are backyard growers, are so jealous

    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!
