Just my opinion first time Autoflower grower what an easy way to bump into flowering and not have to worry too much about strength or burning your plants
Been using Dr Earth grow and Bloom for some time now. Only problem I had at first was timing when to switch from grow to bloom. I time it so I feed the last grow when I switch to 12 12. In about 2 weeks I hit them with half grow and half bloom. After that it's full bloom every 2 to 3 weeks. I only use half of the recommended dose. When I grow autos I use FFOF and usually feed bloom once when I see pistols.
