Whos using this method?? I did add Kelp for Trace Minerals, and 1 could also add Azomite

I tried to mix a 19-20-39 formula as close as possible. Im pretty sure Im very close. I used a basic guide on how much to use per acre.

Base was 3.8 cu/ft Promix Bx.
I used 19-19-19... 3.65oz
0 -0 -60....2oz
Kelp Meal 300 Grams
51 tsp Lime...
2/3rd tsp Calcitic Lime x 1/3 tsp Dolomitic. Level tsp. Not Heaping.

Water with Plain Water, and 1- 1.25tsp Epsom Salts per 5 gallons water. Seedlings get 1 tsp. Larger veg plants get 1.25 tsp in veg around week 5

1st/2nd week flip/flowering slightly up magnesium to 1.6tsp/5 gallons
In 3rd/4th weeks of flowering on an 8 week strain I feed Monopotassium Phosphate 1 tsp per 5 gallons, and feed every watering for weeks 3-4 only. Also slightly increase Magnesium. Week 4 gets 2 tsp/5 gallons,

Weeks 5-6 gets more Magnesium 1 Tblsp/5 gallons water.

Weeks 67-8 get 2.5 tsp per 5 gallons.

Basically all I did was use plain water, and increase Mono Potassium Phosphate and magnesium at certain times.
