You can consider ditching the LUSHGro Aquas or lowering the dosage first. You have most of the things covered with the rest of the things you already have. Your fishes should provide the rest (you have quite a bit for a 2 footer but I think its still OK).
If you suspect it is circulation problems, then experiment with your output pipings. Be it using the rainbar and try to shoot them across the tank or using a lily pipe and blast them around the tank.
I don't know the plant mass though you have quite a plant list for a 2 footer.
