DWC Green Crack

*Thing 1 is my best performer and what I will be using to refer to this plant * Thing 2 is my less performing plant (dropped the rockwool and almost snapped the seedling, saved her just in time) After 2 weeks I Finally got these plants into my Hydro buckets. I had started with three seeds, and only two hit the stage where they popped out of the soil, the third one was stunted at a sprout and never popped out of the cube. I finally got around to transplanting them into the Hydro buckets after a bit of stretching because I was gone for a couple days. I mixed up nutrient solution into R/O water And set them up with an air pump. One weekend to the Hydro buckets and they still look really nice and green, no signs of burning.
