Your parameters seem to be check, you've got decent flow, you use RODI water and good salt, and you're feeding the corals, so I would suspect maybe low lighting is the issue. You posted the spectrum of your lights but what intensity are you running them at? It may be time to slowly ramp them up (maybe 5% per week) and see if your corals respond. You definitely want to be careful though as you're much more likely to kill corals by overlighting them than underlighting.
One other thing that's harder to relay/discuss online without loads more data is the stability of your parameters. While the levels you provided are within the proper ranges, knowing how much they fluctuate over time would help as well. Corals crave stability, so if your alkalinity, salinity or nutrient levels are constantly fluctuating they can never really "settle in" and start growing as they're just stuck in survival mode.
