This reads like what I was about in my high school days. micro grows with CFLs, no climate control, just after something better than the brick weed I was getting my seeds from. Impressive to pull a full pound from them, nonetheless.
Yes, that's a blurple and while you've done some incredible training on that plant, I don't think you're going to hit the numbers you think you are simply due to the astronomical stress you've put that plant through. It looks like sticks with growth tips on it. Not sure you have a position to speak in this conversation.
Now for my turn in giving unwarranted input. I don't buy into the true watts = output when it comes to LED. There, someone had to say it. It's not in the same ballpark, it's not even the same fucking game as HID. I'm running right under 600 true watts in my 4x4, and with two plants, am estimating I'll hit 1.5lb this harvest. 1.5 is optimistic, but had I been more on point with the training, and various other mistakes, two pounds would've been almost achievable, probably shy about an ounce. 900 true watts in a tent? I'd just run a 1k HPS and call it a day. You're not saving any money at that point.
