Thanks for the info man, high level information.
Im at work, but already seen a little bit, hot information for sure, will surely have a deep look soon.
I have a topic of my formula in a Brazilian forum, and things that impact nutrition as temperature, strain, life stage, organic complements (its very common to use earthworm castings in Brazil), maybe somewhere in the future i can translate it to be another source for those who like it salty.
I mix my Plant Prod 7-11-27 with epsom salts and micronutrient mix, in the same bottle, for stock solution.
The other bottle goes with calcium nitrate.
Part A+ Part B nutrient solution. very easy to handle and will meet the requirements of every life stage.
The way i mix it, makes every mililiter equivalent to PPMs in this way;
1ml of my plant prod (7-11-27) mix, is 7ppm of N, 11ppm of p2o5, 27 ppm of k2o…
So its very easy to calculate through nitrogen, the ratio of use.
I also use pourthrough method to keep my eC ratio at comfortable levels, so i can fertilize it almost always.
