I am also a beginner and have had good luck and a few probs mostly with germination a while back, but as far as using Coco-Loco which I chose also, I just love it. I have not added any nutes at all but did start using Cal-mag mixed in tap water every watering at the advise of a VERY helpful grower on here because of leaf discoloration early on, and that took care of that. I am close to going to 12/12 lighting for flowering now and will start adding nutes based on what I here from the pros on here. Mine are in 3 gallon fabric pots under a "Growstar 600 watt LED". These are 7 weeks old and have been topped early and heavily exfoliated a week ago! Hope this helps u out a bit grow friend!
