Recovering from HID, assistance needed.

I have a 90 gallon aquarium with 2.4 wpg (T5). The light fixture is 7in from the water surface and the aquarium is 22in deep. The cal aqua labs co2 checker is 1in from the substrate, and is indicating >30ppm co2. Also the aquarium is heavily planted with Glossostigma Elatinoides, Ludwigia Repens, Rotala Macrandra, Bacopa Caroliniana, Hygrophila Polysperma, Cabomba Furcata, Alternanthera Reineckii 'Rosaefolia', Echinodorus X Barthii. I only have 2 questions so please bear with me.

1. I realize 2.4 is still a little too high but I can only use two bulbs at a time (4x54watt T5's). So, how long of a photoperoid would you recommend?

2. The plants are growing well but almost all the stem plants are getting leggy (Cabomba Furcata, Hygrophila Polysperma and Rotala Macrandra). What am I doing wrong? I'm currently dosing 17ml of ADA Green Brighty Special Lights, Green Brighty Step 1 and Brighty K daily (dry fetrs on the way).

Thank you.
