All that stuff, I have presumed to be from the FF nutrients, as it never hurt the plant before. The hole where the lines go through is light proof, as i have 4 lines actually going into it now and there is no room for light. I figured maybe i did burn the plant or something, not sure how though. I sat the plant in some plain water and took out some of the water from the BB and replaced it with fresh water to lower the PPM. As for the other question about where i get my water, walmart, reverse osmosis. Oh and i figured i may as well try out a water change tomorrow just for shits and see if it helps.
