How long do you let a coral get comfortable in a spot in the tank before moving it if there's no growth?

I have an ORA Gecko Green (acropora) and a Idaho Grape (Monti Cap) that seem to be stalled out. Neither has any bleaching or signs of necrosis, but neither has really grown at all in the 6+ weeks since placing them and I never see any polyps out. The other SPS corals in my tank (Stylo, BN, Cali Tort, Purple tort, Monti Spongodes, Orange Digi, Red Planet) are all showing good PE and growth.

The conditions seem right based on what I've read, but I know that just because I think they should do well there doesn't mean that they will. I'm just hesitant to move them because they aren't showing any signs of dieing off. Hoping that it's just a matter of time and they will eventually come around.

Thanks!
