Do you think i should try adding calmag since she hasn’t had any in about two weeks
No.
Fertigating with just cal-mag is a problem that can lock-out other nutrients. Nutrients should always be fed with all of the elements present in a "balance" with each other. When you feed just cal-mag the concentration around the roots gets too high locking out other elements.

I would just feed your normal base nutrients and bio-stimulants now. It is hard to tell at the end of the plants life what it might need because some of what we see is the plant just finishing.

She will be ready soon and the quality looks good!

so moving forward in the future it would be better to move my Cal mag from my watering days to my feeding days?

Exactly!

This chart gives you the range for balanced nutrients. It is in weigh/liter not EC. It is designed to give you the balance range for the elements in relation to each other. In order for a fertilizer to be in balance ALL of the elements must be present in the ranges displayed. It can be a really big range for many of them. Lets just look at the top 3 for example NPK 100,30,100 - 250,50,300 - 180,40,200 are all combinations that are in balance 50,50,300 is out of balance and can cause lock-outs.

So when you make an addition of Calcium you do not want to apply more than 140 mg/liter

Once you understand balance then you can apply the dilution rate. So you mix up a gallon of nutrients and you check the EC/PPM and it comes out at 1000 PPM on the Hanna scale and you want to feed at 500 PPM. If you mix a gallon of distilled water into the nutrient blend you will have the same balance of nutrients as before but the strength will be ~500 PPM.
