Brown/orange spots, edges curled up and appearing on other leaves.

Purple kush 41 days into flower, about a week ago I noticed these small rust like dots on 2 or 3 leaves, I flushed a few days ago and resumed to my normal feeding schedule. I do a water, feed, water with 2 teaspoons tiger BLOOM, and 3 to 4 tablespoons of big BLOOM to 1 gallon water. The spots have gotten worse in the past few days the leaves look like they're curling upwards, there is lots of yellow and brown spots on the leaves, the brown spots are only on the top.
Looked through a bunch of threads and lots of pics but I need more help before taking action, this is my first grow

First thing I think is calcium deficiency.
