I run 50/50 coco/perlite on an automated system, I feed 3 times a day for 15 minutes. I have a 27 gallon res that is recirculating, change it out every week. I use jacks nutes now, started with gh and they worked as well but I like jacks better, just an opinion. I ran drippers only at first, now I have 2 1gph drippers and 1 valve controlled line per pot, 4 pots total, all 3 gallon. The valve I can open and close, and it ensures the drippers don’t clog while I’m not paying attention, you CANNOT over water Coco/perlite. Keeping your ph steady is the biggest key. I use citric acid most of the time. I also use ro water but that’s my issue with well water, use what’s best for you. Good Luck, ask if you’d like my opinion or further info on some of my grows.
