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 !!
