I was out of the grow for awhile being sick. When i returned to work my helpers had thoroughly overwatered and i inherited some issues, root rot and gnats. Got the gnats under control in short order . The pythium was the worst i have had. I tried all the beneficials like hydroguard and even more concentrated strains of Bacillus Amyloliquefaciens. Usually that will do the trick. This time the plants just couldnt shake it. Out of frustration i tried some clear rez and added drip clean to my mix tank. Within a couple days the plants rebounded and are on fire. I have always added good bacterias and liked it. The plants are on fire since i have been feeding the last few weeks clear rez hypochlorous acid and drip clean. Think i may extend this experiment of sterile dtw coco. Will post some pics when i get a min.
