Great product to go with your Dyna Gro nutrients.
One of the best fertilizer groups out there is dyna gro. Since it has calcium you dont need a cal mag solution and instead need the mag. Which this product provides great value and amazing results. I use their full lineup with complete confidence. This works well after plants bloom. Where i moved to closest dealer is 2.5 hours away. So i was forced to purchase on amazon. have been using Dyna Gro since the 90s. I also use, grow, foliage pro, protekt, and their neem oil which always are the best values around for the most packed nutrient system you can find on the market. No one compares in my opinion. Easy to use, less is more, easy to maintain proper PPM and PH levels. You cant go wrong unless you cant follow the directions. Lots of resources out there about this product. be sure the bottle you get is sealed though from amazon. Had some issues with them not shipping me a sealed bottle from the prime delivery.

Highest Quality - Taste, Burn, & Smell
I start with a Bat Guano Mix that have fert numbers around 12, 12, 12 which is kind of high, but Guano metabolizes slowly and naturally in the soil. Later in the BLOOM PHASE - Add a quarter of what they recommend of DYMAG100 per plant two or three weeks before harvest. Plants easily and quickly metabolize Dyna-Gro Mag Pro - the smell and bloom weight will increase quickly. The fert numbers of Dyna-Gro Mag Pro are similar to Indonesian Bat Guano - clean, low salt formula AMPS UP AN ALL ORGANIC GROWS! Add a SeaWeed/ Humic Acid Treatment in between every fertilization. You will have Competition Quality Buds! Remember - ONLY add a quarter of a cap per plant to a gallon of water - and ONLY one treatment from the middle of bloom cycle - anywhere from a month to two weeks before harvest depending on length of time the plant is set to bloom. A very little - Adds a lot. But because of the high numbers - it can be easy for some to over-fert a potted plant. If you do - flush the plant soil with a lot of water. You can also split the treatment into two fertilization periods - like 4 weeks and 1 week before harvest. Extra rejuvenation and weight gain will occur three days after treatment and extend another 7 days in feeding the growth of the plant.

You don't know what you've found here
This is the reason my legal grow has so much frost. Use more than instructed. It does not burn plants. I guarantee stunning results.

... couple of years ago by an acquaintance as an easy system for plant management
I was introduced to Dyna-Gro products a couple of years ago by an acquaintance as an easy system for plant management. I was quickly seduced by the other big name brands like 'fox ' and 'food for the ' and others. You know what I'm talking about. But complications and additional requirements and strict feeding requirements left my plants looking like stray cats with mange. I eventually went back to 'finishing off' my Dyna-Gro products (Grow, Bloom, ProTekt) and lo and behold, with no effort beyond basic watering my ladies went from sickly to sophisticated almost over night. It's been about 4 weeks since I added this product to the basic three and I couldn't be happier with the results. Dyna-Gro does it all, and for those of us with busy professional lives, it makes caring for our plants quick and easy.
