Cookie kush auto flushing

There's really no reason to flush for 2 full weeks. In soil about a week, coco maybe 4 days and 24-48 hours in hydro. Starting too soon is just gonna steal precious bulking time.

does it have a toxicity or is one building up? If not, there is no need for this. You can let the plant cannibalize itself if you don't want to bother mixing up fertilizer. This assumes a strong helthy canopy -- 2 weeks is fine in soil. 7-10 days in soilless and 48h in hydro? i wouldn't do it in hydro att all. Drastic EC changes aren't good regardless of the grow method no matter what the bro-science says about end of grow flushing but doubly so in hydro context. Nothing potentially clinging to a physical substrate, even if soilless.. with a water res, it's completely devoid of nutes if you empty and refill with water-only. This fucks with intra and extra-cellular concetration gradients that allow a plant's biology to function well. This relates to why: Did you know, if a human drinks too much water too fast, you willl die. For the same reasons mentioned above. Biological processes that rely on normal concentration gradients inside and outside various membranes and cell walls etc will no longer function properly and a massive enough shift will lead to inevitable death. Please, do not try to prove me wrong on this, lol.. more a PSA for any potential obstinate people out there reading this.
