a few spots

Hey there
I was wondering if anybody could help me out on this. I noticed these yellow spots and the leaf edges are curling up on two leafs of my blueberry plant this evening. Its almost been a week since i switched to 12/12, she is in roots organics soil and I am using Foxfarm nutes.
Does this look like phosphorous deficiency? Should I start using foxfarms tiger bloom?
Thanks

Can you provide more info about the plant...pH/run off pH, PPMs, last feeding, do you have Cal/Mag or Micro nutes? Are your leaves stems purplish?

If you been flowering for a week, YES you need to use Tiger Bloom, Big Bloom and a Micro and maybe cal/mag.

This might help you out bro:http://foxfarmfertilizer.com/FoxFarm-Soil-Schedule.pdf
