Holy crap. You've been slimed. That's some of the weirdest crap I've seen. You ought to get those newest slime photos in the problem section right away. I'm really sorry this is happening, considering all the work you've put in so far. I hate to see any MJ plant bite the big one, but I don't know if yours is long for this world. I think you are either getting a huge case of root rot, or some alien has hatched inside your reservoir. Holy cow, it looks likes some holy cows' guts. Do something now! Oh well, tomorrow is when the serenade is suppose to come. I sure hope that does something. I would not chop down your plants at this point, but it looks more and more inevitable. See if you can't get them at least somewhat healthy, then go to flower. Maybe that way you can at least experience some of the fruits of your labor, however small those fruits might end up. At least we can call it a learning experience, and you'll know next time to use a root inoculant and perhaps a fungal preventative. I don't know your res temp, but you might need a chiller. If it gets real warm in there, there is a higher chance of fungus. I'm glad I don't have mold and slime experience, but I wish I knew a bunch about it so I could give you some decent advice.
