a quick flushing question??

ok, so i flushed my plant lastnite and let me tell you it was a pain in the ass. i'm wondering wen i will see the result of the flush?

Belive me it is a pain but well worth it the plants will thank you in better yeild alot less problems such has yellowing and alot of other shit that is normaly down to salt build up from the lack of flushing.listen man if the greenhouse guys flush once a week during flowering there is something in the flushing of plants.could not do it every week but i do flush 4 times during flowering and my yeild has improved i have no where near has many problems.
