Update: I've gotten a couple responses on a forum I contribute to and it seems this isn't Blight. Blight should have distinct outer rings on the edges and CAN turn the whole branch yellow, very fast.
I will give it a good flush with 5.5ph water @ a 0.0 EC this weekend. I will measure the water than drains through until it is also at an EC of 0. I will write a post on the flushing process and record the improvements. Im also going to use Ubiogrow on the plant to see if this helps also.
