could the PH swings be causing troubles for my corals?

Don't adjust pH, especially not for that minute difference. Messing with pH will cause more stress than anything. The drop in pH could be an effect of the low salinity (pH can be slow to react), or it could be an increase in organic breakdown within the tank (loss of corals, loss of microfauna, etc). I think once you get to your target salinity you're best off leaving the tank alone for awhile with no more water changes. Do keep a close eye on ammonia. Otherwise, get back into your regular dosing/testing schedule.

I'm glad to hear the fish and inverts are doing well. The corals may take some time to "come out" again, the fact that their flesh hasn't fallen off yet is a good sign. Euphyllias (frogspawn, torch, hammer) can be really fussy and not come out for many days or even a week.
