DIY Hydroponic Nutrients in 5 minutes

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.

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.

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.
