I picked up both yesterday and man am i glad! I was real close on the 3 5gal BB's i had going,i had the PH good and the nutes were just a little heavy. I redid the 3 and set them at around 900ppm and 6.3PH. Then i made some nute mix for my soil less plants and checked it,man it was way off.Before adjusting the PH it was 3500ppm. I always mixed as per the FF guide,but from now on i mix at 1/4 of what they say.I add each nute one at a time and check after each addition,then adjust from that.I let it sit for a while and check every thing. Now i know why some of my girls just up and died over night after watering.Way too much nutes!
