I've tried most Hydro set ups ,Started with a home made NFT ,then DWC,Auto pots have all ways been the one I use ,its easy growing.But great results, so wont be changing anytime soon.Same with the small amount of nutes I use ,these are only on 1.3,they have been on 1.2 all way up to last week.All I use is canna a/b ,big bud ,ok 13/14 that's it Big bud from week 2/4 ,then pk week 5/6.ive also gone away from using the larger feeder tanks ,that deliver the water ,I use a DWC bucket large one ,and make nutes up daily , I found the larger buckets.Means less work ,but ya get salt build up .I have also given the plants ,big bud and pk 13/14 through the medium this time.Rather than via the tank .And I must admit they loved it,its what I will be doing from now on all the time.
