Hey LAtewood,

You are definitely over watering, and as rasta said it is showing potasium defciancy... but that may not be the only issue....,,,
When you mix your nuts, do you mix them all together and then add them to the resivor..? 'Cause this will cause a nutrient lock.. the nutrients need to be added one by one or at least mixed in a bucket with running water..

How is your PH?
