My current crop looks like crap. My last one did also. I use an ebb & flow system,so the first question is about the watering frequency. I set mine for 5 min on every 3 hrs- I cant do less than 5 min with the timer I have, but it takes 3 min to get the water to the correct height. My PPM is 900 or so (trying not to overdo it), my PH is always 6-6.5. The roots dont look healthy at all, even brown on most plants. I never had problems when doing my own clones, but many are available where I live, so I quit cloning. Any help is appreciated.
