plant a month old you should be able to go full tilt boogie on the nutes. All I have been using for about 1 1/2 years now is GH 3-part but I do have a question, you say Micro and Gro is what you are using but where is the Bloom?? GH 3-part by the label has you using all 3 parts during the entire grow. I use Latewoods Legacy and am done with gro after 2nd week of flower.
