Its literally impossible to tell you what you will yield. Theres about a billion different variables that determine yield, the strain, environment, feedings, style of grow and everything in between. A pretty good rule of thumb is that you CAN achieve roughly 1gram/watt in IDEAL conditions.
I average just over 2 lbs per 1000w light. If I was you, I would hope for 2-3 lbs of chronic plus a half pound-ish of smaller buds. That way if you end up with 2 you wont be disappointed and if you end up with 4 and 1/2 pounds of chronic you will be happy as hell.
