Is my water chemistry good enough to start adding corals?

[Kingston]

Ph: 8.15-8.3
Alk: 6.1 dkh
Ca: 432ppm (Hannah)
Ca: 465 (Salifert)
Mg: 1410 (Salifert)
NO3: 5-10
NH3: 0
SG:1.026
Temp: 79.3

Can I start adding corals? Should I add something to bring Alk up first?
My tank (425g) has been cycled for the past 5 months. Turned lights on 1 month ago. I have a few fish. SG, NH3, NO3, PH, have been stable since cycle was complete. Just started testing Alk, Ca and Mg today in preparation to add corals. I noticed Alk is low. I use Tropic Marine Pro Reef salt. Any advice welcome.
Thanks

I’d say yes depending on corals. Some will be easy going with the low as you get it back up some might not be.

You do need to raise your ALK first. I want mine to be around 8.6 mysrlf. You can raise it easily with some baking soda disolved in RO/DI

Alk will only be a big issue if you start getting stony corals. 6.1 is low (ideally you want to stay somewhere between 8-13, but it is best to stay with what your salt mixes to) so definitely don't do stony corals unless you do a water change or dose alk back up.
