I prefer cns17 as a standalone from botanicare.If you have to ask my suggestion is to use a 1 bottle base Grow nute only start to finish and learn how to read plants and fertilize properly.
Dyna Grow foliage pro is mineral based and Botanicare Pure Blend Pro Grow is an organic hybrid. Just 2 good examples.
Plants need nothing else unless the source water is very soft or ro water then you may need a calcium additive.
Forgot about that one. I never tried it. It is much like foliage pro.I prefer cns17 as a standalone from botanicare.
I have been growing for a few years but am new to organic growing and this is only my second organic grow so I'm still studying and learning about it but I did see and improvement I was not expecting with my first organic grow. I came across this article and was wondering if any cannabis growers has tried this? https://modernfarmer.com/2014/01/human-pee-proven-fertilizer-future/ I don't think we need expensive hydro shop fertilizers to grow top notch plants. espoma tomato tone gave me a significant improvement over the chemical fertilizer I've been using and was very inexpensive when I bought it on sale at walmart
tomato tone has calcium but it lacks magnesium. Epson salt or molasses is a good source for these but thank you for your input.Powdered nutes like tomato tone and jacks are great too. Again. Organic and mineral options.
But watch out as most do not have any calcium included as they are designed for outdoor soil and tap water.
Depending on water source and medium you may need a calcium supplement like I said above.
And in my opinion and testing the advantage to organics is many more micro nutrients included because of the natural ingredients. Seaweed for instance has over 60 available trace elements alone.
Plants can use more than the 17 elements they put in fertilizer.
true. commercial growers have different goals than PU MMJ growers. hydro and HPS will give you the best yield but once I learned enough to be able to produce enough to meet our needs. ( my S.O and myself) then I began focusing on improving quality. in my state I can't sell what I grow but I can give it a way and the people I've given my surplus to claim it is better than what they find at the dispensaries or on the street. but home grown is almost always better than commercially grown. with cannabis or vegetables we just take better care of our plantsI prefer organic for the flavor and terpene profile but hydro and salt fed can be pretty good too and has a great yield.
