Is is possible that in stead of nutrient "Lockout" it could simply not have any nutrients to uptake?

Either way, I will wait a day or two, let it dry out.... maybe let it get to the wilting stage to be sure! Then start giving it 1 cup of nutrient solution every 3 days, or when three inches of the top soil is dry.

Faddenator, Thank you.... I know I could have found that information elsewhere, but then I am left with interpreting it on my own. You have apparently just fixed this problem, so I am VERY inclined to follow your suggestion to a tee.
