There are a lot of people stating they get 2 per light and some even say 3 per light. My best to date is around 2.75 per light. But it is subjective. Even with full environmental controls and CO2 with 640 watt LED's it is hard to get to 2.75 per light every time. If fact it is hit and miss. I recently ran Oreoz for example, 6 plants and I barely got 460 grams of trimmed flower. By the same token I ran Cheeta Piss and got over 2 pounds out of 8 plants. Needless to say Oreoz is on the chopping block. That clone came from tissue culture so not much else I can say out that but just and example of yield and strains.
My opinion is this. Genetics are going to dictate the potential of the plant. I have only ran across a select few strains that will crank out high quality and high yields. All have been clones, I have never found a winner in seeds.
So genetics is #1 in my opinion.
#2 would be environment. Temperatures and humidity are critical to increasing yields. You high temperatures are definitely a limiting factor with HPS. I believe you want to be right around 78 lights on during flower and I would secondly focus on your VPD and get that managed correctly.
#3. Would be nutrients. I keep it simple and I run jacks. Lastly look into adding beneficial microbes and folvic acid to your grows as well as monosilic acid.
So random thoughts. When was the last time you changed to new bulbs? My understanding is they degrade over about 6 months. Also running them as different out puts is not good so I have been told this also degrades the bulb faster. Are you using double ended or single ended as this also makes a difference.
