San Francisco Sour Dough/Glue Dream

starting to see more leaves. one of the seeds we cracked with a knife has started to grow leaves too, looks a bit ill but he was butchered so it's to be expected. there's slight moss growing on the soil so I guess it's still too cold?! ppm reading seems really high but it's exactly the same amount we used last grow and no nutrient burn? so will have to monitor that closely.
