Seeds were germinated on paper towel
Plants were kept under 90w LED in small 150cc buckets for almost 4 weeks, then transplanted to 1lts bucket for 2 aditional weeks before going to 50lts bucket
What you see as week 1 its the moment they were transplanted to 50lts buckets.
I always plant about 4 to 5 plants in the 50lts bucket when I'm pheno hunting.
