Switching from autopot to Drain to waste question

[Paradis69]

Hey guys, first time poster and new grower here
I have a question, im planning on vegging in autopots with 1 gal fabric pot and flowering with 7 gal smart pot drain to waste.. As I learned, autopot build up a lot of salt due to bottom feed, so I would like to know if theres a proper way to flush that all out before transplanting without hurting my plants too much.

using coco/perlite with plebble at the bottom of both 1 and 7 gal
GH trio + cal/mag as nutes
got 5x4 tent ( 4x4 flower and 1x4 on 2 levels for vegging ) under 600 real watt leds and cheap cfl for vegging

thanks a lot !!

Well, in coco people typically recommend flushing with the ideal ppm you want to feed your plants at the PH that you want. That way you flush out the excess, set the PH that you want, and don't mess up the coco's CEC. That's how I flush in coco-basically just feed your normal nutes more than usual.
