Hi guys. I have a challenge with my compost. We had the N-P-K measured to aprox (0,55-0,22-0,13)gram pr 100 gram of dry mass and a pH level of 8,0.
I have a vision of raising the phosphorus and potassium levels with Bat Guano from Plagron and Potassium Sulfat (wich should contribute to lowering the pH, right?).
We have acidic Peat Moss in our bogs and im planing to use this as a 1/3 mix in the soil.
Iv also considered Iron Chelate EDDHA 6% Fe or Aluminium Sulfate but dont know which is the best!
What would be the prefered use and quantity of theese substances and how is the timing?
I heard Iron Sulfate for example need months to react with the medium before the Ph adjustes.
Is it possible as a emergency plan to mix in some nutrientpoor bog peat to acidify the soil?
Soil is intended for Autoflowers by the way. Thanks for all helpfull answers
