Making your own nutrients
I have access to lots of raw materials for making nutrients and know some growers make their own. There was a YouTuber by the name Wizard NPK who had a recipe for Cannabis nutes.
Does anyone have any recipes for salt based cannabis nutes they might be willing to share?
Just interested why salt based being that salt can lock up nutes I was wondering why salt.
Honestly just interested.
That aside hope you find what your looking for.

@mix by salt based I mean raw materials derived from sulphates, nitrates, chlorides and acetates. Lots of people use Epsom salts for Magnesium. This is just Magnesium Sulphate. Some people use Calcium Nitrate for Calcium and nitrogen, this is a salt. Almost all liquid nutrients are made up of these salts and they only really become a problem when your dose for the plant is too high. Then you might get a burn or lock out.
Good question, I do understand the confusion.
@aussie_jim hi mate
im learning about natural farming atm on the side whilst also working on soil regeneration techniques etc ...
ive made plant available potassium (FFJ fermented fruit juice ) using bananas and brown sugar for example as well as lactobacillus for plant health tonic and aid nutrient absorption.
the ideal is to use what you have available and bring in what you initially can’t source yourself ..
im also using some of the RAW nutrients including humic acid (available online) whilst learning ways to make or source them myself ..
feel like I’m still only at the start of a big rabbit hole tbh but I enjoy trying to learn such things lol
How do you grow bro? Soil / coco?
what kinda materials have you locally you’re looking to use ?
Time to pop some more beans 😗
lol Jim i swear I forget more as I get older.
Thanks for the refresher course.

@chillbert sounds interesting. I grow in coco and I am not really concerned with natural or regenerative soils, but I do have a lot of respect for those growing technics.
I have access to potassium humates and potassium lignosuphanate. I know they provide carbon to soil microbes. They are used to condition soil.
The chemists at where I work have done years of schooling in all these and are still coming up with new formulas to combine them all.
Unfortunately in Australia, Cannabis is prohibited unless you’re approved by the Therapeutic Goods Administration to use it as medicine and even then there is a huge stigma attached. So I can’t discuss any of this with my work colleges.
@aussie_jim, Thanks for joining the club. I'm in RDWC atm and just looking at the tip of this iceberg. I'm trying to teach myself the info on the nutrients labels and where their coming from and what they they do. I'm currently using General Hydroponics, and comparing their numbers with others. Slowly learning, hopefully correctly, what and how these nutrients interact with plants. And looking pass the label at what's really in the bottle. The percentages of actual nutrients is amazing. I just need to be more certain about where they are derived from. Like I said, Tip of the iceberg!
But I do like all the colorful labeling and graphics on the nutrients bottles these days. lol It's like Andy Warhol, and Black Cat fireworks had a love kid!
So, I understand your quest and I'm anxious to see what you come up with. I'd like more control over my grows with this knowledge, instead of just stumbling around. Your fortunate to have access to this information through your work too.
So I'll keep watching your post for more info on this. I read where you are in coco and use to be in DWC, I've read and understand coco is more efficient than DWC on nutrients up take and such, so I will investigate that medium at some point. But for now, I'm using RDWC as a tool to learn and see how things interact. The results are pleasing.
Anyway hope your summer was good, your starting Fall now? Sure do miss driving on the wrong side of the car, on the wrong side of the road over there, what fun! peace
And just like that there he is ☝️
@woodi2 really happy to have joined Percy’s, seems to be a great bunch of growers here.
I am not sure about Coco being more efficient than DWC, I always thought it was the other way around. RDWC seems to have lots of variables too. It is something I would like to master, but I still have a lot to learn about Coco first.
It is Autumn here, we didn’t really have a Summer this season due to the La Nina weather patterns over the South Pacific. We had floods, the Summer before we were on fire, so in some ways I guess it’s balancing out.
@meisme thanks! I would be really interested in the ingredients of your home made nutrients and the ratios if you’re happy to share them. Looks like your plants are happy. I had a quick scroll through your diary and didn’t see the recipe or formula you’re using, I will go back and have a more detailed read today.
@aussie_jim Hey mate!
So i have been playing with various recipes over the past year, and my observation is that its all quite flexible. Most elements can be within a broad range, and as long as you keep your dilutions reasonable, you will have a stable well working concentrate.
I found it easy to source these salts locally around here, if you In Australia mate it would be a breeze. Ask away any question you may have. So far I have been keeping mixes very straightforward.
I mix a 3-part concentrate because I find it holds stable owing to lower salt dilutions. Use very low EC RO water, prefer distilled water for the concentrates.
Method is simple. You will need
- 1L measuring jug
- electric kettle (to heat the distilled water, makes dissolving easy)
- Weighing scales, at least 2 decimals accuracy (jewellery scales etc) For the micros even to 3 decimals, they are cheap on amazon.
For each concentrate, in this example we will consider 1litre Concentrate A:
- Heat 600ml of water half way to boil, pour into measurement jug
- Add 79.74gms of Calcium Nitrate and stir very well till fully dissolved. Can take a bit.
- Add 28.44gms of Magnesium Nitrate and stir very well till fully dissolved. Can take a bit.
- Top up the measurement jar to the 1litre mark with distilled water.
- Bottle it up. Done!
Use equal measure of all 3 concentrates.
Above results in a calculated NPK ration of 3-1-4, expect variation in practice. EC estimated to bout 1.3 @ 6ml/l
I used this recipe to grow the plant in my profile pic. DWC. I unfortunately lost it to mites.
@meisme that’s exactly what I was looking for! Thanks!
You didn’t drop the Nitrogen in bloom and bump up the Phosphorus?
I have access to almost all of those. I will have to try this, but I might get a few grows under my belt before I start the experiment.
