DIY Hydroponic Nutrients in 5 minutes

[Michael Huntherz]

I've been using my own mix based on the advice of @churchhaze for about two years, maybe a bit longer, and it rocks in hydro, coco, soil, whatever system you like. I'm very happy with what I learned from this thread and I'll probably continue making my own two part fertilizer from now on.

I use JR Peters' Labs (Jack's) Oasis Hydro FeED 16-4-17 as a base and add Cal Nitrate and Iron DTPA to make part A.

Part B is just Mono-potassium Sulfate (MKP) and Epsom Salts (MgSO4).

I'm pretty sure I've posted it before, but here's the basic breakdown of my current recipe for anyone interested.
N P K
20-16-24
It works great at 1.2-1.8 EC, increasing slowly as they grow and mature. 2.4 EC max, but there's no need to go that high in my experience.
pH anywhere between 6.0-8.0
I usually shoot for about pH 6.2-6.5


I exclusively use my tapwater, which runs ~100ppm and 7.0 pH on average.

It works entirely too well for me to mess with anything more complicated or expensive.

Thank you again chuchhaze, I know that you have be gone for a while but here is a proof that your shit works. I use RO water so I also make my own cal mag plus (I know you hate cal mag )

I tried my mix in coco but I had K toxicity

ps. You forgot to mention hydrobuddy works on windows 64 bit (x64)

thanks again and happy growing

I started making my own hydro nutrients in 2009. It works the same or better (because I'm a better grower now). It's the same thing. These are the ingredients used in AN, GH, Canna, etc.

I chose to show that Univesity of Florida recipe because it's the closest to my own formula, which I have great success with. I don't miss a single thing from GH. I did not want to show my own formula on the first post because it's designed for hard tap water and might not be ideal for RO growers. I have made 19 iterations on my formula since 2009.

That's dedication! It's absolutely insane what nute mfrs charge for a few cents worth of salts. This thread is what this forum is all about.
