Well there's your problem.
You need to lower your pH NOW or risk losing your plants. Bring it down to 6.0. If you don't have pH down, you can in an emergency use cider vinegar added in VERY small increments until you hit the mark, and check back a couple times per day to see that the pH is stable. Check and adjust pH AFTER making your fertilizer mix.
I assume you are using tap water. Calmag is a Calcium and magnesium supplement for people using RO or distilled water. You may not need it, but at the moment you ARE seeing Ca def because the pH is out of range. Andother bonus of calmag is that it buffers pH to a small extent.
Your first project is fixing your pH though. Do it today!!!
