At this point, I've started flushing (X's3) with 6.5 water, then hit w/your bloom ferts (full strength) and 5-1-1 Alaskan Fish Fert (1 TB per gallon) to supply enough nitrogen for the rest of your grow.
Cured my yellowing shortly into 12/12 woes.

Sorry! Its very hard to see whats up with the color of your pics but my guess is you need to add some CalMag to your nutes or spray with epsom salts. You probably have a magnesium deficency.

Sometimes when i dilute my nutes with water and magnesium sulfate (epsom salt)
I put a drop or two of lime or lemon juice to adjust the PH (they also have trace calcium elements)
