But wouldnt that lead to an inaccurate ph if your nutrient solution is off in the end. Technically I dont even grow in coco but I would assume youd might have to adjust ph if your res sits for a bit. But I gues at the same time you can start fresh.This is not necessarily true. You can add your ph up first or after silica. And not have to use it after the nutrients. It does the same thing. You never want to add Ph up after nutrients it can cause precipitate. Adding it before the nutrients takes the precipitate/cloudiness out of the equation..
It took me a few weeks to understand this but I smoke a shit ton of bud and rosin
