First test run grow/Bagseed

Seed was a random bag seed. Popped it at the end of January. Put into a rock wool cube for a month which barley grew feeding only water. Once my tent and supplies started to arrive I transplanted the cube into a small starter pot with a seed starting jiffy mix. Plant has been in this soil now for 2-3 weeks now, started a lot more new growth, and healthy green leaves. The yellowing On first true leaves was before transplant. A new HLG 100 v2 was also just installed on 3/1 replacing a shitty random 45w blurple light which now has exploded with new lush green growth. This seed is just a test run for me to get my feet wet into growing as my feminized autoflowers are in the mail. Mixed my first gallon of calmag & Big bloom at 85% suggested strength on 3/5 and fed a full glass of the solution to plant. Plant seems to respond very well. The ventilation system will be installed into tent on 3/7.
