Ok there are a few threads answering this but nothing really concrete. I am growing in soil but a friend gave me a ton of GH nutrients, the flora 3 part series. How many millilitres do i need to use per 10 litres when i am growing in soil? Also in hydroponics i know the nutrient concentration is slowly increased, does this also apply in soil? Finally i was told to use the GH nutrient chart for hydroponics but divide the the dosage by 4 to get something which will work in soil, is this right? Thanks people.
Yeah i know the lucas formula but it doesn't go big into using it in soil, theres a thing about coco but not soil.
