I'm a new grower and have chosen coco for my medium. Here's what I've discovered: For this new grower, growing autos in coco was a dumb idea. These bastuds are not at all forgiving in coco, which makes it exponentially harder for me to have success as a new grower. I've even come across a few experienced coco growers online who switch to soil whenever they grow autos. I'm still learning the basics of coco and diagnosing plants. So I've started a photoperiod grow to make my life a whole lot easier.
