Sour Mandarina x Rosewater Cookie

PH was stable, around 5.9 for the whole week. EC was 1.3, but for some stupid reason I raised it to 1.4 and the other one (PHENO 2) started to show some stress. I did not know what is happening for 2 days until I finally decided to flush the system. I decided to clean them DWC pipes too and found out they are full mud and old nutrient s*it. No wonder the whole reservoir was unstable all the time. Got some GHE FloraKleen yesterday to make the system perfectly clean again. I hope it makes the sad one live again. No training until everything is stable again.
