because i see droves of growers who practice this. i do coco hydro which this pertains to because we provide nutrients in a semi inert media. what media do u use? im not sure why you post on my thread this way unless ur a coco grower who does just fine not doing that? after all, my blue venom looks like shes going to continue to do fine. according to what droves of growers practice in coco, a low runoff ec indicates an issue but many or almost all of them that post online do not have this issue though it was worthy of a thread, i hope im not messing up the culture vibes of these forums asking contrivertial questions lol makes me question why i started with hydro but wont quit unless all my plants die or dont yield lol.
