good call on the nutes, i re run coco and some grow stones after cleansing it, it has nothing left after the prep for the next run so i'll add nutes... but if your buying brand new soils or cocos that are already enriched wait a couple of weeks... i'll post a pic of my ck a little later she's getting big.. i'm screening her...
as far for flushing i flush at week 2, and 5 of flower then at the end... after the flush i let them get nice and dry then BAAM.... all my bitches love it
my water isn't bad, i did before and i tried without ph'ing and didn't notice a difference
