Flush in coco?

Ive been growing in it for 6years. I just read and read. I read someone say feed til few days until end then obviously lowering ec then use flawless finish for.two days. Everyones opinions different. Just wanted to here what ppl do. No write or wrong.

Soil should be flush the longest, at 1–2 weeks. Coco coir should be flush for a shorter time, around one week or less (watch to make sure your plant doesn’t turn too yellow too fast, because coco does not hold on to as much extra nutrients). During first 2-3 days aim to reduce run-off EC to 200. You could use product like General Hydroponics “FloraKleen” at 5ml/gallon in plain water and no pH adjustment or just use water and maintain run-off EC less than 200

I been growing in coco for years I usually do 1 to 2 weeks. A had flush the ph water till desired ripeness. Do a minimum of 1 week fade. 2 is better. 👍
