I grow autos in FF products as well Frank129. Light warrior/perlite (for seedling) in top 6," then equal mix of OF/HF/perlite. I amend my soil w/Medina GrowingGreen and use their HastaGro 1/2 strengh every other watering during bloom. Works for me. It's easy, I'm old. I like the 6.5ph as well.
What about halpy frog? Im in the 3rd week of using phd water and am wondering when do i use the fox farm nutrients and if anybody tell me when should i use the bloom nutes
