You won’t have to do a flush flush.
Just Ph’d water from now on and no nutrients.

“Flushing” in soil should be started about 1-2 weeks before expected harvest. It consists of just watering and allowing the PPM of the soil to slowly dwindle. You correct problems with a runout flush where you dump the runoff. End of flower flush is feeding water only until harvest.

But if you are ending with a flush, keep potassium pumped up for her. High demand in late flower. It will help density and push her to finish higher quality. So if you use a microbial tea or a liquid microorganism additive, keep that in your water during flush. It will assist in scavenging micronutrients, phosphorus and potassium availability. Without adding nutrients.

According to Bruce Bugbee in one of his videos, flushing is only helpful when there are excess nutrients.

Agreed, with that being said, if I remember correctly, the plants eventually stop taking in nutrients and use up what they have. So it could come down to 1) Saving nutrients from just using ph'd water the last week or so..
2) Saving money from not having to use said nutrients.
But.... it's all personal preferences in my opinion, just read your girls. They will tell you what they need
