imo, the important things in dwc are:
1)res temp
2)ph
3)nutes
4)do (dissolved oxygen)
the most common things that people do wrong are:
1)not pay attention to temp at all. a 3 dollar thermometer will do the trick, an it is absolutely necessary because you have an intense light right next to it. keep it under 75*F if you can. 68* is the target.
2)people misread meters, don't calibrate them right or often enough. don't pay enough attention.
3)nutes. people run too hot, dont flush the res and start fresh every week or two. IMO beneficial bacteria and fungus are a must for me. healthy plants start with healthy roots.
4)most people have sufficient bubbles in the res, but temperature is key. DO in the water varies inversely with temperature, so the hotter the water the harder it is for the roots to breathe. see #1.
beneficial B&F will help alot with #2 and #3 because they make the nutes available at wider ranges.
insulating the res with something like fiberglass would help keep it cooler.
any of that give you any ideas? dwc can be nice and easy if you can change your res easily and completely. and put some good stuff in there, and monitor it.
