Calcium excess or deficiency? or something else?

@macky well recently just two feedings a week apart with the Incredible Bulk organic bloom boost 0.1- 10 - 25.. 1/4 Tbsp per gallon. And before that the only thing I have fed it was Dr. Earth organic bloom feed 1-2-1 a Tbsp per gallon. And as mentioned just twice recently between 3-5 mil of Cal mag. Though the spots appeared before using the new higher PK feed. That is why I didn't think it was a potassium excess. But like I said it's had me pretty stumped. All my other babies been looking green and healthy and doing good. I had to get away from the salt-based nutes and go all organic. All that heavy flushing is way too much work on my old broken body lol.. and don't have a way to know what my EC is... I only have a good pH pen. Just been trying to stay easy and positive with the world falling into chaos, more than I've seen in my life time.. 

@macky I have a large tall oscillating fan that blows throughout the 4 by 8 tent on that end and a short fan at the opposite end, though I never have to close those doors completely. In the stage it's been in, she's been drinking about a half a gallon of water every two days, that's letting it almost dry out but not enough to wilt leaves. She's definitely drinking a little more. Though my critical purple is a bigger structured plant it's not as far into flower, bigger container and drinking about the same. Been feeding them the same, as I was some recently harvested Gorilla, Cindy and Banner. All did great, but this Pine Ex acting up. LOL. I think getting used to what a lot of strains differ and what they require maybe the biggest challenge. Most have been fairly similar, except my first critical purple and this Pine Ex. Maybe I shouldn't give it anything other than pH H20 for a week and see how she does. I just hate to see more leaves showing bad signs, when I should be able to fix it. But I am terribly bad at wanting to be perfection in some things.
