coco final flush & E.C.

First grow in coco and im fucking rockin it. Almost finished and im trying to get my flush on point before i start.
What EC should i be shooting for in my flush? I was told around 0.3 to 0.4 is this about right? I always was told not to flush with pure water due to caution exchange and so on.
Also how long should i flush for? Im going to try for 7 days, seem about right? Like 3 days before flush i plan on dropping the ec down gradually, to the 0.4 i mentioned. Currently feeding @ 1.5ec. Im currently feeding house and garden line: cocos a&b, drip clean, bud xl, shooting powder(about to stop).
And when flushing with a diminished ec (0.3-0.4) should i only feed base nutes(cocos a&b)? Or the additives as well. Excluding the drip clean.


Any help would be awesome and greatly appreciated!

You have the right idea mate 0.3 0.4 is great I would go for 7-10 days in coco gives it chance to leach all the salts out just make sure you have about 20% run off each time you water, glad you rocked it for your first grow in coco

Thanks for the advice dude. Yea my first run with straight coco is going great, with about 2 weeks to go. Used h&g's full line, best nutrients PERIOD. 0 lockouts, super green folliage, huge stalks & alao branches, and a massive root system on every plant i checked.

Most people believe Flushing is running 3X the water to the pot size. With that I never flush but do taper my feeds down to 0 ppm for their last drink.

Might have to give coco a shot 1 day been using dwc lately love the way they grow
