Less plants has helped me increase quality, reduce inputs, and eases my mind. Oh and my yield hasn't changed. I went from 14 down to 7 in my space and just cropped out the same weight, however I actually enjoyed growing just 7 this time, no more praying to just finish!!
Less plants allowed me to spend more detailed time with each specimen, catering to individual needs, spotting problems like ball sacks/ mildew/ bugs. I was on top of everything this time and having less plants helped me. Again, with no loss of yield.
There is a balance somewhere in the middle that will make growing more rewarding. Looks like you have plenty of light, all good there.
