Hey guys, I'm doing my first grow and really need some help, because it was going pretty decent for a while and all of a sudden it looks to be going to shit fast. Set up is 5 plants in 7 gallon fabric containers, started clones in these containers (which I now think may be my biggest mistake). Planted them in pro mix. They are at about 9 weeks vegetation under 1000w metal halide 2 ft from canopy, canopy is at 80 degrees. I've been keeping the PH at about 5.8-6 (going to start raising it as I think too much acidity is causing some yellowing). I am using Earth Juice Grow as well as Earth Juice Meta K (should put my npk level at about 2-1-2. Also using cal mag. I had been watering it with this nute mix every other 2 days (think this may have been too much because of the large pots). The yellowing is honestly the least of my worries. My best plant started rapidly getting brown dead blotches on the leaves and getting purple tips, most of my other plants have had these blotches, also some redish spots as well. My best guess was I had root rot and I got myself some hydroguard which I heard great things about and I have seen the "disease" let's call it, slow since. Some plants upper leaves also have some taco curling effect. I'll attach some pictures and thanks so much for any help at all.
