It looks ok to me. But, fill out the troubleshooting form so we know all the info. It is possible that the water is settled to the bottom and the roots are not down there because it is too wet. But at the same time the top could be dry. I see almost N toxicity in the dark green but don't know your setup.
yes, high N could at least be a future factor. get rid of the humi, and feed with ph correct water only, no nutes...for a week. or flush. temps that are cool also create a backlog of soil dampness, might be a factor:thumbsup:
