It is kind of hard to diagnose problems without piks or history.

It sounds like you were on the light side of nutes, so that didn't kill them, but what about your airstones...If they clog or get turned off..the plant will suffocate.

The medium was river rock in a net pot (with lightproofing over it). The two bubble wands that I have in the root bucket run on 4 60 gallon pumps. Bubbles were visible so I dont believe it was suffocation
BlazeIdo Reviewed by BlazeIdo on . Latewood...help needed Latewood, what could cause instant death to a plant other than over fert. I did everything as I always would with my DWC water change. Fully flushed with RO water. Added nutes, micro first waited 5 min, then bloom,(was using lucas), then sensizym, then calmag, then LK. I addded them at 5M 10B ,10Sensi, 5Calmag, 5LK. per gallon (values are ml). PPm's were at 960, ph 5.8 (checked with two just calibrated meters). I have noticed a bit of black build up on the root base, but I thought it was Rating: 5
