Benzelsanswered grow question 3 years ago I was using power feeding short flowering on my outdoor plants and 1g per liter worked well. But if you go onto their website, and go to the down loads section...wait let me just get the link... https://shop.greenhousefeeding.com/soil.html -Thats for soil. Or go to this one if you want to download a more detailed version https://shop.greenhousefeeding.com/catalogues.html
I was using about 5 grams per plant per week. Started from week 2 in flower and had good enough results I bought more and some of their power feeding grow nutes to try too.
