Had to back the light down because the plant on the right is a sissy weak wussy plant.

What is the Fox Farm Micro and Macro? Are you talking about the Fox Farm Cultivation Nation 3 part Micro, Grow, and Bloom?
If so, the Micro is supposed to have calcium in it but the other 2 do not.
You did say you just flushed, if you didn't have signs prior to flushing then I would just continue your feed and if it starts progressing, supplement with an actual calcium supplement.
