Need help

Dec 22, 2016
Brothers! May I have your attention? I decided to water my pot properly today. After 5 liters of water + Kleen (the coco was spewed) I saw 4.8 pH and 2300 ppm in the drainage!!! Then I washed the pot with 50 (!!!) liters of water + Kleen and finally got 6.4 pH and 180 ppm. So my question is: What ppm should it be and should I water with nutrients afterwards or not? Thank you in advance...
