I run ffof soil, no food for the 1st 3 to 4 weeks in veg. food is 15-0-0. Feed sea-weed extract on off days. Cal. Mag when necessary.Flower change to 3-15-0, continue with seaweed extract. Mix in a ewc tea every 2 to 3 weeks. Best advice is to read up and ask for help when your stumped. When asking a question always try to provide a photo or 2. It can be lots of fun but, I can guarantee you it is more work than most think. give as much info you can when asking questions, just makes it easier. With that said, welcome to RIU!
