Yellow Spots

Hello, so... this is my first time growing and so far I have been doing pretty good. No major issues and I m in my 2nd week of flowering after a 2 month long veg. I have 6 nice bushes going now. The problem is that 1 of the 6 is starting to get yellow spots on it. None of the other plants have this issue. I am growing using a GH Waterfarm system so they are all sharing the same nutrient solution. Any ideas?

Currently plants are under one 600w HPS in an XXL hood. Light is on a closed ventilation system. Temps are steady at 77 max during the day and down to about 70 at night. If I run the AC 24 hours a day I can get down to about 67 at night. Humidity is a bit high at max 65" with a low of around 50%. It fluctuates throughout the day as the AC cycles on and off. PPM is at about 1100 right now. PH was a bit high at 6.75 but trying to lower it over the next day.
