Alright. So my plant (ch9 vintage 2006) was growing wonderfully then we got into some oddly warm weather while I was away at work and came home to a wilted little girl. Water smelled bad. Changed the res and flushed with clean water for a couple hours while I sprayed away what seemed to be some slime. Cleaned and boiled my airstones and cleaned my bucket really good as well. Water hasn't spiked and I haven't seen the slime come back either. I mixed a 2.5/5 ratio of micro and bloom into a 5 gallon bucket and ph'd it and added that back into the res after all the cleaning. My ppm currently is 473 145 of that being from the ph'd tap water so nutrients are around an actual 328. The roots are a little brown with new white growth coming in as well it looks like from the pictures. Any advice is greatly appreciated. Just hope I caught it in time. Ambient temp is currently 76. The thermometer is right by the heater as well. And i'll be turning that lower once the hps comes on in a bit. Water is also ph'd to 5.5-5.7 depending on how much I move the pen and all. Just hoping I can get some input on the situation as well as how to prevent it besides the obvious. Also. Does light penetration cause root rot? I can catch some of the water bubbling under the hydroton out of the corner of my eye sometimes but the plant is growing too low to pull it up and fill in around it. Or could I? I've also added my h202 than usual to try and prevent the same thing from happening. Pictures are included. Help me out please!
