C99 DWC balcony using soundwaves

Sorry to announce that both plants had to be cut. They developed root rot. Don't know if it was caused by the root aphids or what, but I do know that at least the strong pheno was OK before I washed the roots on soap to get rid of root aphids. Probably the good bacteria died and I didn't apply Hydroguard during those days and perhaps that was enough for fungus to invade, or perhaps it was the stress/infection due to root aphids, but basically, one day I was sitting next to it because I have a dining table just there, and I was feeling uneasy all the time until that day I felt as if the plant basically told me it was suffering. So I decided to cut it and upon lifting the lid, the roots just broke on their own and separated, indicating the degree of rot. This also explains why I was finding pieces of root in the water. This was my first DWC and I'm basically never gonna grow again with it. It is a pain and it feel unnatural.
