It's very shaded, might need to post one with a flash or fix the white balance some. I cannot really see much except for some new buds on the stalk?
I did the change to get my Ca. and Alk. back in balance, my Ca was at 520ppm and Alk was at 11.7dkh. Now its down to Ca 425ppm and Alk 8.1dkh, was it too drastic of a change? I've heard that water changes are the best way to get things back in balance.
The new chem is much better but I wouldn't worry as much about the change you've indicated. Lowered Ca
doesn't have much of an impact. Where most of any problems will occur when dealing with the chem is the change it causes in pH. Did you happen to check that?
