So many factors plat into this its impossible to tell. Maybe one plant gets pests and that will mess it up or one plant gets nutrient burn or root rot.
If all the factors at play stay stable, and the grow goes well. It will depend on how big you let your plants get before switching to flower.
I have grown out some of g13Labs seeds before and I loved them, the Blue Cindy was a A++ strain. lovely growth patterns, smells and smoke. Lots of top shelf buds for me in the smaller grow I did.

The maltezerz I grew from them was less happy in my setup but i'm sure it would thrives in a hydro environment.
one thing to note is you have a lot of wattage in that tent for just two plants.320w x3 = 960wats. You could easily but that in half and still have a great grow if your looking to be more conscious on your electrical use and save some money. The g/w ratio of 1:1 is good goal but not as easily obtained. For you to hit that. you would need the plants to yeild 960 grams or 2.12pounds of dried herb at the end of it. That would be a record harvest if you can do that. Don't focus to much on it and just have fun growing.
I started off saying to myself. ok 1oz a plant min. once I hit that mark I raised it to 2oz then 2.5-3oz I use different numbers for autos vs photoperiods but its the same thing small personal goals and not getting to upset if I don't hit the mark but always moving forward with new ideas and understanding.
Best of luck with your grow. I would ballpark anywhere from 1-3oz a plant atm from what I see if you keep up the good hard work.
Happy Growing!!
