Hi big plant was vegged over 2 months , the problem one wasn't vegged long roughly around a month . Been feeding them both the same mix , biobizz nutrients and soil is also biobizz light with perlight. The big plant is directly under the 600 wat hps Light and I've raised the small plant up with something so it's not in the shade of the other plant . Been feeding small doses of nutrients about every 5-6 days strain is a free seed I had with my seed order the strain of it was special queen seeds kush # 1 I think or maybe it was special kush # 1 queen seeds
