think that could be part of the problem?

Hmm, a 400W is supposed to cover a 4' x 4' area, yet it's confined in a 15" x 15" space, lined in mylar on 3 sides. The LED was 10" above the aero system, while the MH was 24" above. If it were any closer, the plants would suffer greatly or die from heat stress. The MH is 14" higher than the LED, and has almost 70% more wattage, as well as a much greater potential to carry light energy over long distances vs LED. I've known plenty of growers who only use HID, and most of them run between 12" and 24" from their plants, so I don't see the height as an issue.

Bloom will begin in a few days, and I will be removing the plants from the MH all together. I will be installing glass and ventilation to the MH, and taking one of the plants from LED, to place under it. Then I'll start bloom, side-by-side with the same sized plants, to give a pro comparison. The MH will be able to go lower with ventilation and glass. Anyhow, it takes time, but the switch will happen soon.
