I recently switched back to growing in coco/perlite after having severe trouble with it about seven years ago. In my own opinion here are some tips I would consider while you are getting started.
-Coco has a fun element to it called CEC or Cation Exchange Capacity. I wouldn't dare to explain it better than it has already been done numerous times on the web, but understand coco substrate will act with and hold specific nutrients differently than just about any other medium I can think of.
-Soil=BigPots=BigRoots=BigBuds Coco=Small Pots=Full Roots=Big Buds, so when switching to coco I was advised by one of the nutrient companies head of R+D to use 1 or 2 gal air pots, and never let them dry out. This seemed counter intuitive at the time, but what about air in the root zone I thought? Don't the plants need a dry out period? He explained that keeping them fed many times per day, the exchange of new water in the root zone brought new oxygen, and when the pots are small, the plant fills its roots out so well that it has no issue taking that many feedings per day. He also explained that the previous issue with the CEC is far lessened when the pot is not allowed to dry. All this ends up in my opinion to being one of the closest methods to a constant feeding massive yielding DWC without the high risk of root issues.
-pH is paramount. Before switching back to coco I was using Sunshine Advanced #4 mix and with my nute program it needed no additional pH tinkering. I literally went a year without testing a pH, was amazing. Now, even with my same mix, I must pay extra attention to the pH of the res as the swings in coco can be quite unforgiving. Grower of over a decade and I almost kill a plant in the flower room last run due to two days of bad pH.
That's what's on the top of my head this morning anyway. Happy Growing
