Right on Sixpack. I will be doing this tonight when I get home from work and will repost.

I may have overlooked it but what are you using as a buffer ? for your PH ?baking soda ? Or potassium carbonate ? The soda will cause issues like that but I agree with what garrigan posted. Looks like nute burn not lockout which, is probably occurring now. I use a shop vac to pull off excess drip water from my drip pans. It makes flushing easier and faster when I’ve experienced similar issues. You don’t have to wait just water and vac repeat.

The problem started before your ro water, though, correct?
