Wedding Cake Hydro

Very happy at the start of the week. Noticed mid week that nuit burn continued even after returning ppm to 1150...so dialed back further to 1000ppm. Noticed ppm increase after a flood. So clearly right after the stretch, I needed to drop back the nuits until buds start to pack on. Not considering a flush, but it’s not out of my mind either. Discovered a meter battery was weak and not showing the true strength of the nuits. I was feeding a booming 2400ppm! By the end of the week, nuits were back under control. I’ll hold steady 1050-1100 ppm or 2.2EC according to my meter with fresh batteries.
