Trying to Fix 3part feed

So I took a job managing a large coco based medical grow. They had on site the 3 part advanced system and a gh Cali magic. After trying to get them happy using a few variants of the standard 3 2 1 and Lucas I decided to break down the numbers like organic soil fertilizing.... holy shit guys the 3 part is toxic plant death! I see now why the canna works so much better!

Basically it is mostly potassium, then tons of people add terpinator and potassium silicate as well ... damn..

So I got to looking at the gh Cali magic... pretty much a good base imo I use 500 ml in 200 litre res.

150 ml. Bloom and 75 micro get me at 1.5 ec then I add super natural super boost 1-3 tbs ,it is 11-49-9 and has complete micros as well except boron. So 1/4-1 tsp borax. I add a bit of Epson salts for sulfer and more mg if I want moreppm ....bump up ppm with a 0 50 30 in mid bloom and lower the super boost (high ammonium nitrogen)...

Works

Be careful with borax. It will drive your pH up in a hurry.

Better test pH soon.
