My first suggestion is to use regular seeds instead of feminized as they tend to be more vigorous and hardy. The downside is there will be some males to deal with.
If you go feminized, choose a strain that yields on the heavy side, pick good genetics (ILGM!) to start. Don’t reinvent the wheel: what you want to do is use tried and true methods and keep the plants right in the middle of the ‘sweet spot’ for them. With that in mind; I like media like coco and Promix for big growing plants but soil will get you there too. If soil then use one optimized for weed. If doing soilless choose a good nutrient line and only use their product if possible. This is to maintain compatibility and PH buffering. PH and TDS meter along with cal solutions. I am assuming you have some means of managing temps. Humidity. Using a VPD chart (Vapor Pressure Deficit) to maximize growth.
Read some journals. That can give you an idea. Here’s one of mine:
Good water is important. I use R/O and many others do too.
