You're right. There are a LOT of differing views on when to start adding corals. I really don't think there's a definitive anything as far as reefing goes. Just too many variables.
Here's my experience. I started adding corals to my 125 at about the 2 month mark. Zoas, acans, pocilopora, and stylophora. Most everything survived, but I really didn't see any real growth or good coloration until about the 6 month mark. At that point it seems like everything just took off. I'm sure there are reasons why this happened, but I couldn't pinpoint anything. I think ultimately it just took that long for the tank to find it's sweet spot.
That being said, in my opinion your tank is still too young to start adding corals. Though it may not be apparent, your tank is still going through some pretty big changes. I would wait until at least the one month mark and start with very hardy corals. Just my opinion, and like you said, there are a lot of opinions.
