Well, the roots aren't really black black, but they are definitely stained a dark color from the LK. I don't suspect the roots because they pretty much look the same as they always have. There's really no way to get the water out other than fix my bins, but I was hoping to do that after harvest. My flower room has some serious design issues but I don't think its possible to change everything that needs to right now while its up and running. Also, the yellow started when I was using the new bins where all the water drained, so I don't think its part of the issue, but I could be wrong.

The leaves turn completely yellow, from the edges in, and stay that way for a day or two, then shrivel up completely and turn brown.
dejayou30 Reviewed by dejayou30 on . Nitrogen Mayday! My nitrogen deficient plants are getting worse! I don't know what to do! Pretty much all the large fan leaves of the one plant have been consumed, and now my best looking plant is starting to turn really yellow towards the top. I am on day 23 today. What the F should I do? Rating: 5
