Frankly, I think you are faster than those who are starting off with 3 ft tanks...even me take atleast 2 months.
I think you are more into Corals (SPS and LPS), so you must meet all their requirement and what makes it even more complicated in my view is that you are running a nano tank which is much harder due to various reasons (i.e water flow, lights, temp and etc).
My advice to you is go slow else you might cry ....just my 0.02 cts worth
