Lighting is more important than feed at that level. To get that you need to push your lighting hard. Like a DLI (Daily light interval) of 2000. Some plants have a light sweet spot before you start losing yield. But like corn, cannabis will use all you can throw at it (before you bleach it). With that much light, your air circulation, transpiration, water and feed regiment will be very intense. If you've ever grow a plant to harvest in a tiny container, you know you have to water and feed several times a day. Same for something like what you want to do.
I don't have the stamina to do that for a few months, so I'd absolutely automate and babysit a drip system otherwise you'll drive yourself bonkers trying to keep up at that pace.
This video is worthwhile to watch.
