I am still having the problems that I posted about in Plant Problems 3, and now it is on many leaves on each plant. I am not sure what is causing this still.
Here is the update:
I have new pictures since the problem is getting worse:
Yellow Leaf 1 (Day 2), Yellow Leaf (New Growth), and Mottled Leaf (Day 2)
Today I flushed the system with 10 gallons of PH adjusted water and further diluted the nutrients with another 3 gallons of PH adjusted water. I will wait and see if this stops or slows down this problem tomorrow.
