If you have multiple plants try stopping now on one then keep feeding on the others to see what actually works. Do not follow the one answer people saying "stop now" with no explanation as why to stop now. I don't stop until the last week at least this is peek time your plants need food to finish,if you really want to learn look up active transport and plant osmosis that will give a definite answer. Once you understand how the plant eats flushing becomes merely removing the chlorophyll which gives us the harsh taste people mistake for "non-flushed" cannabis.
Like I said if you can afford it try on one plant and compare to the one you didn't stop feeding the results will amaze you I guarantee!!
