C99 DWC balcony using soundwaves

Had a root aphids invasion. It seems they were the ones responsible for the deficient growth on the weaker pheno. They starting reaching the other one that was super healthy and I had to try to eliminate them. I read online that the roots needed a soap bath to drown the fkers. I did so and the weaker pheno looks healthier than before though I'm not sure root aphids were eliminated. I also noticed its roots have darkened probably as a consequence to the attack so it will probably never be as good for taking nutrients. The healthy pheno, unfortunately, did not seem to like the soap bath and has been wilted for 4 days now. Many leaves have died and I'm not sure if it will recover. I have ordered pyrethrin and The Amazing Dr. Zymes to treat to get rid of the aphids once and for all. Will probably apply the treatment on the weaker pheno and only in the bigger one if it gets better.
