As far as I understand, leafs were sent in the lab.

-what part of the plant were they taken?
-how many of them?
-under what conditions were the plants cultivated?
-were any other parts of the plant tested (stem, flower, roots, buds…)

thanks for the great quality of your blog, each time i come here, i’m amazed.

black hattitude.

Your statement is quite incorrect.

Specifically, what methodology are you referring to?

The difference is, Advanced Nutrients programs contain the correct and balanced amount of phosphorous in them.

With 3+ being the new 2+ with a lot of our satisfied, and prospering customers our products can speak for themselves. Our research efforts have helped to make this possible.

Phosphorous is a main base in DNA. Your levels of phosphorous are absolutely unrealistic. Try the same test with truly DRY material so you don’t have water skewing your results. Any real scientist with any Chromatography experience knows that.

and order a bottle!

NO you don’t have to be a med patient
YES you will be able to get it at you local hydro store
YES it does what it says!!

GO BIG MIKE KEEP IT COMIN!!

Could Erik also be able to comment on the study laid out here by Big Mike?
Specifically, how did this study determine the optimal level of nutrients for a MJ plant?

Presently, some indoor growers are applying too much phosphorous because the recommendations for applications and formulations they are using from have been based on outdoor field agriculture practices, which simply don’t apply directly to indoor gardens. In nature the soil is very deep, and roots do not occupy the entire body of soil as they do in containers, beds or systems found with indoor gardens. Phosphorous leeches from the rootzone in natural soils quickly, washing away from the contact zone with plant roots, as it drains with water further into the depths of the earth. To ensure a healthy supply of phosphorous, outdoor conventional field agricultural growers do a sort of “over-application” of phosphorous, because it has been determined that much of it will be quickly leeched away from the plant roots; what remains at any given time can be taken up by the crop. From this, we can learn that excessive “P” values in our N-P-Ks are not necessary for indoor growers, where Phosphorous maintains a high level of contact within the root zone of plants grown in artificial soils and in containers, beds and systems commonly found with intensive indoor growing environments.

Now what affects can excessive Phosphorous levels have on crops? Firstly, excessive levels of Phosphorous can create nutrient imbalances in the root zone, and consequently inside the plant. This creates a form of stress in the plant which can diminish yield potential and increase the plant’s susceptibility to problems such as insects and diseases. Conversely, it can also be said that a slight stress induction from excess Phosphorous may have some benefits in the late bloom/ ripening phase as the plants reach maturity.
