This looks like calcium deficiency to me. Increase the amount of CalMag you are adding to your nutrient solution. If the bottle says 1ml per gallon then the next feeding add 2ml per gallon, essentially doubling it for the next feed.
Second feed add 1.5x the amount then third feed back to normal. If you still see more spots like this happening over the next two weeks you will need to increase it more.
I hope this helps.
