Alright so here is my grow journal with pictures of the seedling in trouble (at bottom, post from 9/6): HERE! Essentially, Pineapple express at Day 17. rDWC set up. I came back from a 3 day trip, and saw the plant. Pulled back some of the clay pellets, and the rockwool was pretty much soaked. I'm thinking it could be this? Any help is appreciated!
