My tap comes out at 8.5. I ph down my water and feed mix to 6.5. 7.0 is not ideal, but that shouldn't cause a big problem.
I'm used to Ca def looking more like splotches or speckles. Yours looks like more focused around the veins on the leaves.
If you supplement CaMag, the Ca comes from calcium nitrate, so you're adding nitrogen. You don't want to overdo it.
Are you measuring the ppm/ec on your feed mix?

So you recommend I add calmag but exactly as the bottle says? And do you recommend a good ppm tester

I use botanicare calmag+. The recommended is 3ml to 5ml per gallon. I err to the low side on all my nutes. The recommended amounts on the bottles tend to be too high.
When I make my mix for plants that are at your stage in flower, I try to be around 1000ppm. Full strength nutes will put me closer to 1500ppm. Thats with 250ppm tap water.

And I’m feeding the calmag with every watering or only on days I use nutrients?

The plants are not finicky (well some strains are more forgiving than others). It's easy to overthink it and mess them up from trying too hard.
You should be aware of what is in each of the nutrients/supplements you are feeding your plants. Too much of something can cause problems just like not enough can cause problems. For me, it's better to err on the side of less, so as not to overdo it with too much.
Botanicare CalMag+, the plus variant of their CalMag product, has Iron added in addition to the CalMag. So just be aware that you are supplementing Ca, Mg, N, and Fe with that product.
