Recommended Growing Conditions:
1)PH Value: 6.0~6.5 in soil; 5.7~6.0 in hydro/DWC. More cal/mag and water+nutrient less
2)The rate of photosynthesis and transpiration are directly affected by temperature, humidity and airflow. Even though plants grow in many extreme environments, they thrive when given the perfect growing conditions. The perfect temperature and humidity for your plants are found between 75°-85°F and 50% - 70% humidity, with plenty of airflow to replenish CO2.
My understanding is that a calmag deficiency looks more like spotting than what I see here. When I had the same issue, calmag, it looked much different.
I'm new so I don't have much more than that for you.
As @Seamaiden has seen fit to abandon you kids re. calcium; allow me.
She would tell you to foliar calcium chloride. (see tomato end rot spray)
I have used it, and there seems to be no down side, and may fix your problem for the moment.
Then you need to figure out why it is your girl isn't getting what she needs.
pH maybe, but I think she looks nice.
Other than those blebs.
Spray her.
