Is that 3.5 dkh on the alkalinity? Maybe placement on the tank in regards to flow and light? Also if you just added them they could still be adjusting. I had a toadstool mushroom that took three weeks to come into it after I got it and my green star polyps took several days to even open.

Calcium is WAY to high, should be between 420-460. Alkalinity is way to low, should be between 8-12. SG should be 1.025-1.026.
LEDs are good. Might shock incoming Corals. All depends on what your LFS had the Corals under.

What do you do to bring the calcium down and Alkalinity up?

add small amounts of baking soda.

if the 3.5 is meg/l alk is fine. If it's dkh then it is low. a teaspoon or two for every 50g or so will raise dkh and lower calcium. Just take it slow and easy.
