Take some coco from the root zone. Soak that in a pretested water solution. Swish around for awhile...and even let it sit for awhile if you like. Then test! That is true results. Not runoff!
sorry guys i forgot about this thread. It turns out that the bucket I had been pouring the run off into was the same bucket I had poured some excess canna A & B into!! I then measured the pH and EC of this water which produced this result.
all is good!
