Hi .. i haven't grown since i was a kid .. grew some nice photoperiods ones back then .. I decided to grow again since Canada legalized Recreational use.. and i heard a lot about autoflowers that i decided to start with them. I purchased a 4 autopot system because I travel for work and sometimes I am gone 4 or 5 days.. I have been trying to research for GH Series nutes which chart to follow Drain to Waste or Recirculating with this system. My plan is to grow in Perlite and Coco. Can someone help me out please?
