Copper like leaf discoloration only on fan leaves

Quick question, can anyone tell me what this looks like? my ph is 6.9, the ferts I give it are Jacks 15-30-15 and it is 4 weeks into flowering. It has only attacked the fan leaves and the other portions of the plant has none, not even the new growths for the buds. Thanks in advance! I know the jack's has all the micro nutes so it makes me wonder if its a bad genetic, the plant is a big bud

Boron deficiency is orange, but really orange, almost like neon. There could be a heavy Calcium deficiency or perhaps multiple deficiencies. Are any of the spots crispy?

yes they are a little crispy, and the the greener portions of the leaves are not.

what ferts are you useing

I'm using jacks 15-30-15, but today i switched to 11-35-15 and it comes with Micro nutes as well. I also supplement purplemaxx too.
