day 11 and I messed up big time somewhere as when I decided to water my plant for the first time with nuts the EC run off was at 5.6 although my solution fed was 1.1 (0.3 EC of Mills calmag, 0.1 EC of Rhizotonic from Canna and 0.7 EC of Coco A+B from Canna.) I then decided to flush with RO water until I get 0.9 EC run off, which I did but which I also forgot to PH which was at 7.5 (I roughly flushed 2.5 liters of 7.5 ph RO water.) Now I see this white vein in the middle of my first true leaf.
