You got a buildup of salts there, and a magneisum issue, most likley from build up of salts. You should flush your res out every 2 weeks max.

Your water temps, try to get them down to 70 and no higher.
If your roots are brown above water you got issues.... take a picture of the roots and post it here, cause if your roots have issues your plants are going to show problems too.

Sorry to tell you, but that IS root rot man...... better get rid of that asap.

Get some hydroguard phasan20 after you rid them of this issue.... your going to have to clean out your stuff, anything water touched.

Get some SM90, will clear your problem up in no time!
