I have a question about using gh flora series nutrients with auto flower strains. since there isnt a veggatative stage do i start the beginning flowering ratio as soon as there is white hairs? my plants are only 4 weeks old and only about 5 inches tall. right now im using the early veg stage ratio so i dont cause nutrient burn which is 1/2 micro 1/2 grow 1/2 bloom. thanks if you can help
