You are working with very low light intensity. Even with two 1000W lamps in my cylinder, my watts per square foot value was only about 20, or 2000W for 8.92m². This is considered to be very low, others would use three times as much or even more!
I believe you will have better results near the top if you use a 600W lamp. I fear you are starving your plants for light.
Even now I'm using 900W of highly efficient COB LED light for 24ft², or 2.23m².
I can put 600 right now .. I have ... but ..)))) I'll let you disagree, colleague, by trial error, I came to this conclusion. Maybe I'm wrong, of course.)) Time will tell how we are told.))

We forgot that we are children, locking the soul in the body
We are sure that we must obey important uncles
Selling the soul in the clubs, breathing not weakly
We sleep and see dreams, how our mother caressed us
We do not need an answer, we need to cool down
Do not change our world useless running
And you're so close, our time is pouring
I need to forget myself or my heart breaks down
Stumbling, we lose sight and peace
Everyone will hide their smiles, but they will not say how it was
We can not hide, so that we can not see
It is not so easy to understand, but it's not insulting to us.
In the night, when all the stars light up on the fir-tree
I ask the dragon to be serious with me
In my little heart there is a big word
I want to live and become healthy again
I'm flying to heaven, embracing your neck
I see the planets, while the catheter in vienna
While I hear a voice while I see faces,
But the world leaves my firebird
