Budget Organic Auto Grow

I have been steadily raising the light height about 4 clicks every few days. Blue Cheese plant is very short and squat at 18 inches but very dense with flowering sites. The Northern Light is 28 inches with great shape and symmetry. No real changes to the environment. SF2000Pro still at 60%. I spin the plants every few days and water them with bubbled tap water only. No fertilizer or amendments have been added or used since the initial soil prep.
