I gotcha. I have grown under the Amare for over a year and done a lot of testing under it. I'm not trying to tell you how to grow but just offer some advice as I do have a par meter too. The lensed cobs that close to that tall cola will eventually burn the shit out of it if it's not already. In your situation I would leave the lenses on as the plants are far away from the light but I'd take that one lense off that's above the tall plant/cola. It's a good way to adjust the intensity of the light with uneven plants.
Did you have the light that high the whole grow? when I have my lights to high they stretch like that one did. If they start growing uneven I train them to be as even as possible. The difference of even 12 inches of light height drops the light intensity up to 60%.
