You need to get those T5's within 6 inches of the plants. Even closer with airflow between the tops and the lights. I would use your CFL's as sidelights. Especially on the inner side with no reflective material.
So you have 10,000 lumen with a 4 foot T5HO 2 bulb and maybe pickup another 3K with the CFL's. Just a thought...and what's with the really wide leaves on the little one?
What is the strain?
