Grow Mediums Flushing coco and ppm/tds ?

[idiopathic neuropathy]

Flushing prior to chop/harvest. I know some people said it doesnt matter to flush. Im using synthetic nutes.

Phd water only--Flushed one plant for 5 days now and ppm runoff shows 900.
Flushed a second plant for 2 days now and runoff showed 110 which is what my tap water is.
Trying to make sense of this. Seems it should be the other way around.
Any ideas why ?

No, but I'd sure be interested in the answer!

I feed my plants organic Blackstrap molasses at the end and until I harvest. I don't do 24/48 hours of dark either.

Seems like you overfed first plant.
You don't do anything with flushing. Plant need nutrients at the end more than ever.
Never flush coco with straight water, always some Ca/Mg and little nutes.

So taper down or reduce nutes before chop even though im using synthetic gh nutes? On a side note their are so many schools of thought...confusing as fck
