Whomever has told you to wait...is the person who is not primarily interested in money.
Patience is critical in this hobby.
Cycle the tank, challenge it with some dead raw shrimp...or even feed the tank as if you have fish...if you the water quality stays good, you can be confident.
I would lower your specific gravity to 1.025-1.026. What are your other parameters?
In the end, you can probably consider adding some hard fish or inverts before then based on water quality, but that advice, overall, is spot on.
Don't rush.
