After an initial 5gal/pot flush on thursday and friday(half the plants each night), I did another runoff test on saturday. Runoff EC was back up to ~4.0 on the plants I tested. I decided to repeat the flushing procedure, and was able to flush them all again on saturday.
I did runoff tests on a few plants on sunday, and now the EC is around 1.5. Hopefully I've managed to flush the bad stuff out. Probably tomorrow or wednesday, I'll do a few more runoff tests. If the #'s still look good, I'll water/feed at full strength, and hope for the best.
The plants appear to be recovering, but they got pretty beat up(and week 4 of flower) before I could run down the problem. I may have to let the 8wk ones go longer. Lesson #1: ALWAYS test my soil BEFORE I place valuable plants in it! Lesson #2: Just because the manufacturer says it MUST be something I'm doing wrong, DOESN'T make it so.
Wonder where all those salts came from. Amazon has a high coco content...maybe it was a "little" salty"? I'll definitely be making/testing my own mix next run.
